HEAD PORTING TODAY,Q's
Wow,i know why its expensive!Well been at it all day,one's looking pretty good.yeah,one.Any way,i didnt have them machined yet,but i'm wondering if i got into the valve seats some am i ok??I really dont want to ruin my heads,so how far is TO FAR??
The bumps are gone,guides teardroped,smoothed ports[not polished exhaust yet]I'm leaving the intake ports a little rough.Polished my chambers some.So,what do you think?For a street/strip combo,is this enough?I'm still got to fill crossover[and finish those ports]and weld divider,thanks,BO

Can you make ALL OF THE PORTS exactly the same?
Do not get into the seats too much, unless you want your machinist to install new valves. Do not cut heavy on ANY port wall that is over the center of the cylinder. How far is too far? Can you show any pic's? I used to polish chambers, I now feel it is a waste of time. Extra $ for a paying port job only. Also chews up chamber volume. Chamber volume is compression. Compression is HP. Can you e-mail me the pic's??? Jim Last edited by Warhead; June 11th, 2009 at 05:14 PM.. |
