I just mean a lot of heads have decent amount if untapped power waiting for basic hop ups yo unleash it, the lowy stock 318 head can do 300 hp with mild and a least 325 hp wild setups before porting etc... From what I understand the work done to the /6 head is gonna make the build hp wise.
Yes, the head had 1.74/1.41 valves in it, & I pocket ported it. It was done with no flowbench at the time, so I was conservative with My approach, I know now it had room for much more improvement.
