Purchased a new valve spring compressor tool #648615 from Advanced Auto here. It could not budge the Comp springs on my 454. So I bought a large C clamp and made my own. Works great.
I was surprised to find lots of oil in the passages between the #4 and #5 exhaust over to the intake manifold on both 360 heads. Should I be? Cracked heads? Blowing in from the exhaust stroke? Thanks.
According to the fine gentlemen over at another forum dealing with heavy equipment, the values are a plus or minus affair, so, for the rears, it is 425 foot pounds plus 125 or minus 85. Seems like a huge spread, 210, to me.
