New HP #'s 419whp & 379wtq My mods are:
SLP Stage III Heads @ 10.6 CR 2.08/1.60
Comp Cams 234/228 .576/.571 113lsa cam
Steelworks 1 3/4" longtubes w/ 3" cats
SLP loudmouth 2.5" duals w/ xpipe
ASP pulley
MTI 78mm TB
K&N fiter
3.91 gears
The pulls were made through the cats and full exhaust and gears. The car made some more power but we pulled some timing and added some more fuel to be more conservative.

JS- Yes this is an SLP cam. I bought the off the shelf kit. They had an optional 236/236 .595/.595 112lsa cam that is supposedly good for another 10-12whp. I didn't opt for it. I should have because the one I have now drives really easily. The car really comes alive at 4K.

Yes they are 243 castings and IIRC the heads are $1995 fully assembled. I think I paid in the neighborhood of 3000 bucks for the entire kit heads/cam/double roller timing chain/high flow oil pump/gasket kit/cam/pushrods. I'm doing the Iron block 402 soon which is why I chose the heads. I may have gone the AFR route but 10 mos ago when I bought the heads they were the new design from SLP so I thought I'd give them a try.
