EPS cam with PRC stage 2.5 5.3L heads? Is anyone running, or planning on running an EPS cam with PRC Stage 2 5.3L heads? The reason I am asking is because it seems everyone is matching EPS lobes with LS6 heads and making good power.
I would like to run ported heads for the higher flow rates but I'm a bit turned off from PRC LS6 heads with the 235cc intake runners. The PRC 5.3L heads have smaller intake runners (220cc?) that would probably match my 230/238 112+2LSA cam quite a bit better and the lower price & additional compression would sure be nice
. The only problem is that I don't know if the runner shape of the 5.3L heads vs. the LS6 heads would "affect" what makes EPS cam make so much power and torque. Is there still a difference in LS6 vs. 5.3L runner shape after porting is complete or are they nearly identical?
Any input is apreciated! Hopefully GEoff or TSP can chime in as well...

Thanks for the correction... I guess I should have paid attention to the dates of posts from you guys saying 237/230cc etc. Appears it was changed to 225cc in 2008... this definitely helps w/ my decision, I want to keep those velocities high!
