Cylinder head decision for 318

C2ndLTpigeon said
As I have posted before, I plan on using a huges whiplash camshaft in my 318, the engine is a 1974 production and I am thinking about changing the heads. The only concern is the whiplash cam works well with stock compression and Im not sure how much more compression will rise with a set of performance heads. Also the engine uses flat top pistons and I also want to make sure there is no valve interference with the bigger valves. The heads im looking at are from indyheads, and are their Indy X series.

Looking to get better flow and bigger ports. If compression rises a tad would I still be able to run on pump gas?

Thanks

better flow and bigger ports are fine but you need the problem is stock pistons and 8.6 compression don't sound like a good combo to me . good luck . you have to build a complete package you just can't slap onsuper heads without the rest of the gear toback it up use the flow and bigger ports . wtf do iknow not much /good luck with whatever you do
