Try the stock rockers (maybe Harland upgrade) with a 62cc chamber for decent copression.

 

Depends what compression ratio you want, of course. Decide that, then you can tell.

 

With that big cam if your considering patriots go with their 59cc head.That high compression shoud be great with that cam and I think they have good ptv clearance also.

 

Our LS6 heads are a 64cc chamber. We can deck the heads if you would like as well. To clear that cam without flycutting, you will need us to set the heads up for that cam with factory valves and you won't be able to deck the heads. If you have any questions, please shoot me a PM or give us a call. Sometimes, we get so busy, we get behind on emails. I know I am way behind at the moment!

 

would 64cc heads be ok? im basicly looking for about 450-460 ish to the wheels. and be as reliable as can be...

 

We build the stage 1 ls6 heads complete with extra piston to valve clearance. We can build you a 61cc chamber ls6 head with MS4 piston to valve clearance!

 

Checkout gm high tech performance issues from a few months ago we built a stock deck ls6 head with ms4 & made over 540flywheel horsepower with no decking!
