So right out the gate I have a blown head gasket on my 72 olds 350. I kinda jumped the gun one day when I took it for a quick emergency drive with the PCV valve unplugged and the breather closed off(please don't make me explain why) I'm assuming it just built up enough pressure and blew the gasket. Didn't really get hot so I think I should be ok to just replace the gasket and move on.
I do however have a perfectly nice reconditioned set of olds 307 heads, on the off chance that the heads on my 350 took a some damage, what would the harm be in putting on my 307 heads?
I've researched it a little bit and have heard things like it wont add much performance, the intake valves are smaller, there swirl port heads etc. Considering my goal right now is more reliability than performance I should be safe right? My only fears are I'll either just put my 350 heads back on and have problem's, or I'll use my 307 heads and have problem's.
Suggestions?
