Guys I'm finishing up the all new Version 2 of the PRC 5.3l Stage 2.5 cylinder heads!
These new PRC V2 5.3l heads will feature all new cnc maching, new ports, new chambers, & aftermarket rocker clearancing standard!
We're currently finalizing a larger 2.5R valve/port option for guys wanting 317cfm+ air flow from a $1400 a pair cyliner head!
Here's the pics of the new rocker arm clearance & PRC logo!

Looks great Jason! Are you going to be offering these new heads with the cam combo just as you did with the old stage 2.5 PRC 5.3L heads? If so, what will be the new combo price as I had already planned on getting the Heads and Cam (MS3) combo from TSP in about another month, but if these are just slightly more, I will be all over them.

I'm doing the same combo in June and would also like to know how it's going to affect price.

I'm curious as to how these will work on a cam + full bolt on stock cube LS1 as compared to the Stage 2.5 LS6 head. Have you guys conducted any tests to compare the two?
I've done a LOT of research on the 5.3 heads and it sounds like you guys are still finding ways to squeeze a few extra HP out of an already solid set of heads!

Guys the previous version of the 5.3l head is still very nice! I would not replace my older PRC 5.3l heads with the new version. Both setups work really well, we just updated the PRC heads with a few new features. ![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
There's definately no doubt the leader in budget minded performance cylinder heads!
We're working on package pricing for the 2.5R 2.055 / 1.60 valve setup right now!!
