Valve sizing
Posted: August 17th, 2021, 2:49 pm
With a reasonably mild 4.7 build based on a 99 block and 0630 head, i had considered bumping the intake valve size up to 1.94 or 1.97, probably a swirl version and a swirl stock size exhaust. is this even worth the trouble? I am guessing any gains would be negligible and maybe not worth the cost? Any thoughts? TIA
