Performance Induction's NEW cylinder heads This is the brand new Performance Induction, large runner cathedral port LSX cylinder head. Not the best pictures but I don't get paid to take them.

Cary will respond with details on the hardware, valve sizes and other info. I just figured a few pictures would be a good start...

Sorry guys but since I will never be a sponsor here, I can't post pricing or too much info without ramifications from some people. After all, I'm not Curtis Boggs you know. I sent Patrick a PM to make sure this thread would not vanish, especially since Performance Induction *is* a sponsor and asked to get these pictures from PRI posted up.
I will say upfront, these are not inexpensive. Forget the cheap imported head prices or thousand dollar ported LS2 heads. These race bred cylinder heads are priced higher than AFR and TFS but have a whole different architecture than the typical inline valve LSx casting. Valvetrain options will also effect the overall cost. They are being offered as a semi-custom built head with the base price for fully ported castings and valves. Depending on the valvetrain used, valve type and material, as well as the other peripherals will add to the base price in order to arrive at a finished price.
The 215-245 port volume heads use LS3/L92 rockers and the 275 RACE series heads use the LS7 rockers. The 215-245 have the six bolt fastener option but the 275 have that standard. The design allows for serious push rods to fit without worrying about breaking into runners. Many, many features on these heads that I can cover but might be best if I handled it on another forum. Don't want to deal with the wrath of Big Brother...

Great looking heads from Cary. Thanks for posting up the info Ed. Wondering if Cary's single plane intake will be a better option than the Super Victor for an all-out application?
