They are an old set of 320cc patriot freedom series heads.
The cam is a Bullet custom grind solid roller I ordered to go with those heads years ago for a 496 I never finished due to lack of funds ha ha!!
Hence the reason for “budget” heads.
So... I had that cam and all the valve train parts to go with it for those heads from long ago. (Springs, titanium retainers, locks roller lifters ect.)
The truth is I spent more on the cam and components than I did for the heads.
A lot of this 572 build wasn’t on purpose, it was a collection of parts I have had from my years of gathering and hoarding bbc stuff when time and money permitted.
That’s the long way around telling y’all what the heads were. But I figured the next question would be why? lol!!
