Hooker seems to have done OK with truck headers.
By Dave Shoe - 05/02/2004 1:43:35 AM; IP 216.243.176.34
I'm not to smart when it comes to truck headers, but I understand Hooker and Hedman truck headers all cater to the low-exit exhaust port of hte C8/D2 heads. C3 heads would likely be a mismatch with C8/D2 compatible headers. I say "likely" because some truck headers have oversized flanges that port match to both high exit and low exit heads.

The RPM is a nice but imperfect match to the C8 heads. I see no need to clean the mismatch up at your RPM levels. The CJ intake was a mismatch to both the CJ and the PI heads, and both ran well.

C8 heads have a well flowbenched runner design. I'd stick with them as long as the air velocities are gonna be well within the operating region you are looking at.

JMO,
Shoe.
