Head Flow Numbers

[sheckyZ28]

What do normal GN heads flow compared to that of the TTA heads?

Intake side isn't much different giving 210 CFM pretty easy. The exhaust side of the TTA sucks! We flowed a set of pretty worked Manley valve TTA heads and about 150 CFM was max. A TR head will give that stock. Ported and worked a TR head will give real close to 190 CFM on the exhaust side.

Intercooler...aren't you the one who ports heads and stuff? If so, how much to port a set of heads, and install bigger valves and new springs? This would be for a daily driven car, with my combo.

E-mail me and we can hash it out.

hi, do you know the flow rate between gn heads ported/w big valves and out of the box/champion-alum? from 2000-rpm to 6000rpm? and what is your take on back cutting the vavles? thank you mcponch.

All those numbers are on Kevins site. If you search for him under username "Kevins" it is on there. As for back-cutting the valves it helps on the stockers but not Manley's or Ferrara.
