Never heard of those heads personally. Let me ask you this...why would by a car with heads that no one has ever heard of? That would be enough to steer me away lol

Just a typical guy that doesn't know what he has, just what someone told him. Look for the 3 digit casting # on the forward top side of the head. Don't beat the guy up, I have know people who didn't know what the "LSx" on their intake meant.

I think the ported stock castings they sold were Patriots.

Since I will be tearing into this motor I may be able to identify these heads, anything that I should look out for. Slp did have a stage 3 pkg but didnt include heads. I guess I will find out.

I wasn't trying to sound like a jerk or anything, so I apologize if it came across that way! Yes the casting number on the front passenger side head would be a good start

I can see no casting number on the heads. The valve springs are silver and are dual springs with a silver retainer. I will be taking them off in the next few days so I can check my lifters so I will post some pics, however I cannot find any casting numbers whatsoever! maybe there will be somthing on it.
