hemi vs non-hemi
as a powersports mechanic im confused how the hemi is less desirable. Hemi style heads should make more power so what's the catch here is it just availability of compatible parts?

Stage 4...
So far it's been amazing. Bolt on ready to go. I didn't have any clearance issues with anything, but do yourself a favor and get a valve spring compressor. 40# valves cannot be done with out it.

14cc head!? Actually 17.5cc you...
So I recently bought this head. Last night I decided to do a cc test on it as I though it look a little deep/big for a 14cc head turns out it cam pit to 17.5cc resulting in a compression ratio drop from 12.7:1 down to 10.9:1 that's alot left on the table. Please do not sell this head as something it is not. Head is currently at the machine shop getting reworked will inform you on how much was milled to achieve the 14cc I was sold....
