Does anyone know how well these heads will work with a T-Rex cam?

new set of Patriot Performance stage 2 LS1 cylinder heads. These are based on 853 castings (they are center bolt valve covers). They are new and still in their original bags and packaging, which I did not remove to take pictures for fear of wearing off the protective coating applied to the parts. They feature 2.02/1.57 valves and 67cc combustion chambers.

Bump... I have similar spec and flowing heads and the same question. Help is appreciated.

While I can't give advice on the heads... I can say be weary of the seller, he seems a bit sketchy with no pics and the way he describes them.

If they are unmilled they should work. You will want to check PTV with the bigger valves though (should anyway) because the Trex barely clears stock heads.
