cool...

Ok here are my thoughts...make sure the pushrod hole is not tapper'd.
turn up some aluminum stock, make dowls.
put some lock tight on the dowls and press
them into the factory pushrod holes.
then remachine new pushrod holes..
i was gonna offset them anyway..
then you can modify the port entry to accomidate
better air and hit your C/sa..#s

it sure seems to have taken alot to unshroud the valves...did you happen to cc them before and after? did i gain alot in cumb.chamber CC?

you had to press all new guides in the heads? ouch!
