I've got a set of KB flat top pistons waiting to go in so that should raise the compression ratio a bit.
I've got a choice, I've got the stock 318 heads that will probably need (at the very least) a light skim, so while the machine shop is in there I don't mind putting in bigger valves and doing some port matching.
I've also got a pair of bare 360 heads that look like they've already been skimmed (don't know how by much?). If memory serves me correct the combustion chamber volume is 65cc. If I use these I'll need to get valves, springs etc. same as the 318 heads so no change there.
I've read that the larger port runners and combustion chambers in the 360 heads can really hurt the compression ratio if used on the 318.
Would I be better off working on the 318 heads?
Every article on building a hot 318 seems to focus on using the 302 casting heads or using Magnum heads which then presents a whole load of other issues.
I don't really want to go to the expense of aluminium Edelbrock heads.
If the Magnum or 302 casting heads are the way to go, has anyone got a set?
I will be using an ally 4 barrel intake and headers.
Sorry for so many questions but I only want to do this once and I don't want to cock it up.
