Guyz did anyone try the PRC 2.5 LS6 64CC heads? i've seen many that have the 5.3 heads but I dont want that much compression due to the low octane gas we have available.

When i searched the forums I didnt find any reviews about them. I'm guessing the LS6 has around 10.5 CR on stock gaskets without milling?

thanks and help is appreciated

 

Call and ask Jason or Brian 806-866-0734

 

LS6 or LS6 "style" heads?

 

LS6 heads with new GM cores from the looks of it. TSP is selling the LS6 heads outright for $999, so it seems to jive with the $1999 price tag.

 

LS6 243 casting number..

i looked again at the PRC 5.3 stage 2.5 too, i really dont want much compression, is there a thicker layer gasket i could use to lower it a bit?

 

Bad idea.
Just use a Ported LS1 243 casting.
The thicker gasket is one of the worse ways to lower compression.

 

We have bigger chamber options for the guys not wanting alot of extra compression

The LS6 heads are working pretty well right now, we're trying a few more tweaks in search of some additional flow, but the last set flowed 260cfm @ only .400" lift!!
