Head Porting basics

Thanks.
when you trim the push rod pinch do you cut it straight, as compared to the port entrance or cut it at a angle to match the straightening affect of that wall?

I cut it in line with the straightening of the wall......................

Cut it straight....the only reason the #'s go up a lil is cause your doing the same thing the clay radius or radius plate does, but when the intake go's on poof go's the #'s, even if you open the intake up to the gasket on that side...it still has to then go around that 'speed bump' PR pinch.

It's not necessary to get the #'s.
