pro comp ls3 heads can anyone enlighten me on the pro comp ls3 heads? i know they cast there own version of the ls3 head, the cnc versions look nice, but they are really cheap in price and as the saying goes, you get what you pay for... does anyone know anything about these heads?
If your looking for a proven aftermarket casting LS3 head checkout the PRC 250cc LS3 heads. There's been lots of great results with them! We're also finishing up a stock size 262cc runner that moves right at 380cfm~!

Just do a google search on "pro comp heads ls1tech" and you will see the things people say about them. We had one guy from pro comp that was trying to show of their heads and when we backed him in a corner I don't think he ever posted back. I told him I have heard numerous times from guys who have removed pro comps from their engine and put on other named heads (Brodix, AFR, TFS and such) and made more power but I have never heard it the other way around from nobody. Then he moved on to durability and we shot him down on that too.
The castings most of the time are porous and thin. I weighed my Stock L92 heads and they were almost 50lbs total when I shipped them off to be ported. I have heard guys saying they weigh in at 38 lbs. My question is how do you remove almost 12 lbs of metal from a set of heads and it looks like the same heads?

pro comp heads Junk heads. People might talk about the power they made was comparable to other ls3 heads but lets see how durable they are compared to other rectangular port heads.

At what lift does this head move 380cfm?
How many exhaust cfm?
What size valves does it use?
Will it use ls3 or ls7 rockers?
These are all questions that I have asked before but maybe you are a bit more willing to inform us all now you are getting closer to finishing these heads?

Damn Jason! You guys are bringing some serious products to the market. Will these new heads have stock valve angle? You are making it hard for US customers to decide which of your (PRC) products to buy.
