Junkyard 5.9L Magnum + Edelbrock LA heads build

I have found that if the jy engine has some miles on it the ring gap will be sufficient for small boost 4-6 psi, just run a good headgasket -felpro or cometic but I’m not sure of your budget or goal.
The stock headbolts should be good also, there 1/2” but since you already have ARPs then use them. I waiting on the Pre magnum (91) in the Truck to have an issue so I can start on my 360 magnum for it. So far I’ve broken everything but the engine!
