I’m confused. Are we talking ootb as sold x-heads, W2’s, Speedmasters, Edelbrocks, TF, Bloomer, Indy etc etc? No porting, no valve size increases, no tubing etc?? A hogged out race head with big valves sold as an ootb standard offering would mean any Home ported, or porting service, a race shop reworked head counts or no? Equal sized valves for any other being compared etc ? What counts and what is excluded so we know what’s being compared. Total cost for each setup as run. I need clarification
