I never even looked at the date of the thread! I just noticed 302 and said to self, that's what I have! The original heads on my donor engine were cracked between some of the valve seats and Hughes was adamant that with the combo I was considering prepped 302's would be fine.
A set of ported of 302 heads is fine for the power your looking for, but there’s way better heads to swap to, there a bunch of people that push these heads for whatever reason. But you got them and wouldn’t sweat it, you’ll make decent power.
