So just wanted to see what everyone thinks or feels about larger valves. Numbers are just a reference, I have a spare head and will be chopping it up soon to get exact numbers..
So this is more towards the ohv and being FI.keep in mind the ohv has very small valves and I will be stroking it and running 4" pistons.now lets say you have .200 of clearance for the valves to go larger.what would be best for FI and the fack my motor will be larger and stock is super small.
So would you
A-increase the intake valve .200 and leave the exhaust the same?
B-increase the exhaust .200 leaving the intake the same?
C-increase both .100?
D-increase the intake larger say .150 and smaller exhaust increase .050(or any other equal number)
E-increase the exhaust larger say .150 and smaller intake increase .050 (or any other equal number)
What whould you do and why??
