I jumped on the end of the year head porting deal offered in the Hot Deals Section on this site. so...

Before Porting, ask asked Jeff (Modern Cylinder Head) to flow a port for me. IMO it would have worked well, just as the MP crate engines come with a cam in the .525-.550 lift. I don't have the flow sheets in front of me, but the flowed pretty darn good down low, and mid lift.. From right off the top of my head flow numbers...

Just letting people know, I was under the impression that these heads flow 360-370 cfm OOTB, which doesn't really even come close.

Intake
.400-306cfm
.500-321cfm
.600-332cfm
.700-336cfm
.800-337cfm


exh
.400-209cfm
.500-198cfm
.600-198cfm
.700-198cfm

Boy they really shined above .400 lift hu
I believe they will pickup a little flow after his cnc port program has run it's coarse. I know 100hp is mucho to pickup on a head porting job, but I'M willing to bet it will be right there..

Gains....
+100cfm intake
+60cfm exh

If anyone on here doesn't know Jeff or the work he does, he is top notch, right along with his work...This isn't the first set of heads he has CNC'd for me, and probably wont be the last.

Happy holidays guys
