Is there any specific manner these heads should be ported or should my machinist just apply basic porting technics? I've never had cylinder heads ported and not quite sure what to expect in regards to actual porting results or what type of performance gain I will be getting? Thanks for any insight/tips. 89/5spd/167k

If you find out anything, would you mind passing it on to me. My block goes in May 12th and we've been trying to get some kind of direction.

i ported my exhaust ports with a dremel and wow i wanna take them back off and do some more the exhaust ports have a big step behind the valve that needed smoothed out i left intake ports alone but will prob do them too if i take them back off. look for the thread with the head cutaway pics and youll see the pics what im talking about

I wouldn't worry so much about porting the intake/exhaust passages, just some light cleanup should be fine. The chamber is what really needs to be ported, see this thread for pics http://www.sccoa.com/forums/showthread.php?t=45085
