LS6 "style" heads?
LS6 "style" heads? Do all aftermarket LS6 heads begin life as GM LS6 heads or do the companies cast their own. Take THESE for example. Are they true GM heads with added goodies, or are they made by Patriot Perf. from scratch?
damn, jrp answered w/o saying to go search? 
AFR is the only company SO FAR that casts their own heads. edlebrock/linghenfelter are currently R&D'ing their own castings as well. PP's LS6 style head is a great bang for the buck, it flows pretty well, and its cheap(as performance heads go). however as more cars get LS6 castings stock, the LS6 castings should go down in price(as they will flood the market, won't be such an exsclusive item). also the competition provided by edlebrock should help with prices as well(i'm hoping anyway).

i just got off the phone with a guy from PP and we talked about the LS6 style (LQ9 heads) and he said it was basicly the same as the LS6 head but with bigger combustion chamber BUT that they could do that head in a 64 or 58 or 59 i think if you want
so im assuming that it is every bit as good as the LS6 head if they can bring the comustion chamber back to the same size as the LS6
he said that hey dont shave the head to do it but rather build the chamber up and then use the cnc machine to machine the combustion chamber to whatever it needs to be

We begin with a GM OEM LQ9 raw casting. These castings are +.050 on deck hieght. We then weld up these heads, heat treat to OEM specs, and machine them. During the machining process, .040 is taken off the deck. This leaves us .010 to mill for clean up after our CNC work is finished. This makes our process unique in that after all of our maching and CNC work is done, our heads are still at the factory deck hieght. No other company using GM castings can achieve this.
We believe that with our free MLS 6.0 head gaskets and new head bolts included with every set of heads, that our products give you the most power gained per dollar spent!!

pdd bent the valves b/c he mis-shifted and over-revved the engine. he had installed an different shifter i do believe, and on the way to work he was playing around and was not used to it, resulted in a missed **** = overrevved motor = kissed pistons. you can ask pdd, but i think thats pretty much what happened. but i understand what you meant now about the gold coming off. i didn't eat my wheaties this morning, so i'm a little slow today.

I believe you would be much happier with our custom designed, race-proven .650" golds than with an "off the shelf" spring.
