Here they are in their final form ready to be machined. All porting done. Flow #'s are on a 4.500 bore, 2 1/4 pipe on exhaust. Took the pushrod pinch out so that the cross section is the same or slightly bigger than the throat, and short turn is bigger than both.

Some guys wanted me to pour the intake runner...it measures 315cc. The chamber measures 74.5 cc with no milling yet. Yeah, I do alot of chamber work

After this, I'll post some pics of the oil drains we drill, and a little pushrod hole enlongating
Here's some flow #'s and some pics....
