I need some quick advice. First of all how much should the push rod holes in the head be opened up to accomodate 1.65:1 rockers and where should it be cut? Second what angel(s) should the valves be cut.
Set up: 400 .040" over, zero decked, Edlebrock RPM cam (RAIV) and RPM manifold and performer 750 carb., 6x-4 heads cut .060" to 86 cc's, opened up for 1.77" exhaust valves, ported (flow unknown), hedman headers, flowmaster 2.5" exhaust with h-pipe, dynamax super turbe mufflers, 2004R trans, 4.11:1 rear.

Open the pushrod holes towards the rocker stud approximately 3/16". Blend down into the head about 1-1/2".
The valves should be cut at the stock angles. 30 degrees for the intake, 45 degrees exhaust.

Like Will said.
Open the Pushrod holes on the TOP-SIDE toward the Rocker studs. I will be doing that tonight. Grinding bit at Sears Hardware are about $2.50 for "VERMONT AMERICA" Made in Japan 5000RPM Max rated. Thus far they held up as good as my $45 Snap-On bits at 28000RPM. H.I Stud

Thanks. I don't know if I will go with 1.65 rockers or not. Just want them open in case I want to later. The heads are off now so the time is right.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
