I have a set of 243's laying around im thinkin about haveing some machine work done to. (Ported, polished, etc.) are many people runing setups with stock heads? If so what are they having doen to them and what flow numbers can be expected on average.

Im still on stock heads but still put down close to 500whp and have ran a 10.80 pass before....You might as well get some 205cc Afr's for the amount of money your gonna spend on porting and polishing.......



Just my 02.....

I have stock 243 (untouched, unported) just changed valve springs and retainers (Comp Cams 921 spring kits) only and if I was going to get them worked on it would be with a proven reportable company with CNC machine.

Feel free to give us a call.

We have plenty of experience with porting stock castings. We've gone a best of 10.30s on a stock bottom end and 9.60s on a stroker. Both were normally aspirated.

We have a very good handle on the situation.
