i've had these laying around in my garage for over 7 years and would like to get them ported.back in 2001 i made 462 rwhp with the svo intake npi cams and 14 psi.
I had mine hand ported by Chris' Heads in Valencia, CA. Contact Jim Grubbs Motorsports in Valencia, CA at 661-257-0101. Ask for Jeff or Jim and they can put you in touch with Chris. He did an excellent job hand porting my SVO heads and they out flow much of the competitions CNC ported PI offerings. I will post my flow chart as soon as I scan it. I had mine port matched for a PI intake because i don't have the SVO manifold. I have a thread with my engine build on this forum if you are interested in having a look at them. :beer:
