    Valve seals for camel hump heads?

    Yep, I hear ya. The true typical “budget” option would be vortec heads, but then by the time I got them machined for bigger lift, better springs, new intake manifold etc, there goes the “budget “ option. There’s lots of cheap junk aluminum heads out there that are Fleabay specials but I would...

    Good info- thanks!

    Valve seals for camel hump heads?

    @Rickf Part of the reason of taking off the valve springs today was the hope that a machine shop could measure the spring pressure to tell me if they’re stock or not- he said he couldn’t because he couldn’t tell what the installed height was supposed to be. He recommended just getting a set of...

    Valve seals for camel hump heads?

    They have a more budget line (I saw your suggestion as well) for 625$ a head without the bells and whistles. The only thing I’d have to do is change the springs since they’re made for roller lifters.

    Valve seals for camel hump heads?

    Compression test done. Pretty good results- all are north of 170 with the highest being 182.

    Valve seals for camel hump heads?

    Oh yeah, I’m aware of the different configurations. It’s entirely unlikely that someone would spend all the dough to convert it from a 350 to a 327 from a generic mid 70s 350 truck block. My money is on this guy was sold a “327/350hp” and someone put a set of camel hump heads on a 350 to give...

    Valve seals for camel hump heads?

    But more to your point- if they start looking pretty suspect, I have no problem dipping into my savings and getting a set of budget line AFR heads for it. One thing I’m going to do is when I have the rockers off, put a straight edge along the top of the valves and see if they’re pretty even- if...

    Valve seals for camel hump heads?

    That’s a wonderful question. I bought the truck with a rebuilt 327/350hp just put in it with nothing hooked up. Except it’s not a 327, block says 350. So I asked the guy I bought it from about that and he came clean that he didn’t rebuild it, that it was purchased already rebuilt. So at this...

    Valve seals for camel hump heads?

    I found some of the Pioneer valve seals OS-450 that @Ricko1966 suggested on eBay in the stock size for cheap, they’re getting harder to come by so I ordered them up for 17 bucks and free shipping. I figured if they’re the wrong size, I’m out less than the cost of 5 gallons of gas. They kind of...

    Valve seals for camel hump heads?

    That’s a good idea. I like that better than a flimsy rope. On second glance, those are just damper springs, I don’t think they’re true dual. Do stock heads usually come with damper springs? I’ve never looked closely, honestly. Lashed lots of valves, never looked close.

    Valve seals for camel hump heads?

    Well @Ricko1966 I tried to get a camera in there to see if I could see any hint of a seal but the only thing I accomplished was verifying that I had dual springs. I’m assuming those would not be stock. I’m planning on getting a valve spring compressor (I already have an air compressor fitting...

    Valve seals for camel hump heads?

    @Ricko1966 looks like those might be on their way out. Only some various smaller websites offer them, O’Reillys says unavailable. Of the websites they are listed, they are listed as both .530 and .610. Do you know which one is right? Thanks.

    Valve seals for camel hump heads?

    Sounds like a plan. Those don’t need any mods or machining? Sorry, there’s just a lot of information floating around out there. I need to find a good video to watch. Actually, I’m going to make an effort to find one today that explains it all. It’s not rocket science, I’ve just never had to mess...

    Valve seals for camel hump heads?

    I pulled my plugs to check the color, and I noticed the dreaded oil on the threads. The outside of the heads below the valve cover gaskets are dry. It does not visibly smoke from the tailpipe. One plug looked a little black, but not coked up with oil. The rest were normal. Engine has less than...

    What have you done to your square lately??

    Ordered up some transmission lines from Inner Tubes, and today I’m going to stop by the parts store to pick up some ATF hose and FI clamps so I can make the connection from the external cooler to the radiator trans cooler provisions. If anyone has a flaring tool that they recommend let me know...

    rebuilt sbc Oil pressure

    Wix is a good filter. Can’t speak to to the filter bypass specifically, but if it hasn’t been changed and replaced since break in, I certainly would. Do you know what pressure it was running before rebuild?

    rebuilt sbc Oil pressure

    Morning coffee spitballing here. Maybe pull the pan and check the oil pump and make sure the the pickup is nice and tight on the pump housing and/or not clogged with break in lube. Would give you a chance to look in the bottom of the pan and look for debris anyway. How soon after break- in was...

    C20 suburban lowering issues

    I feel like I’m one guy that got away with it, mine seem appropriate. But then again, I never ran mine in isolation without a stiffer shock (KYB Gas-a-just) so that may be masking what would otherwise be too soft a spring. Mine are CPP 2.5” lowering springs.

    1972 GMC C10

    Thanks! We’ll try that. We did try manipulating the shifts at the transmission itself and no dice there. The guy is out of town this week so we won’t do our usual day out there, we’ll take a look next week.

    Transmission line locations

    Never mind about the thread size- Cold Case website says 5/16 inverted flare. Still have my ears open if anyone has input as far as flow direction.

    Transmission line locations

    Rather than start a new thread, found this one. When I got my truck, the radiator trans lines were already disconnected. The radiator was shot for the most part anyway, so I had replaced it with a cold case aluminum. I utilized the existing aftermarket cooler that was already there in front...

    Radiator condenser combo.

    Cold case has them in stock. https://www.coldcaseradiators.com/product/77-87-gm-pickup-truck-21-ls-swap-aluminum-performance-radiator?sku=GMT556A21LS I think if you use the code “Vice grip” in checkout you’ll get free shipping.

    Hey, happy to do some digging- I just copied and pasted what some other dude wrote (sorry, should’ve been more clear about that).
