1.94 11/32 +.100 valve diameter.
90,70,45,35
3 angle is fine as long as they are right angles.
Find the spot between maxed bowl 90% and maybe a little small still like 85%, Finesse that last bit after the valve job if necessary so you can see better if need be.
Thank you very much for your input. I was planning on 11/32 valves, did you mean .001 oversized stems? I know the exhaust ports & bowls are really strong on these heads, same three angle grind and bowl treatment?
