Default LS3 Heads on LS2 Valve clearance

Looking for a little help. I will be putting LS3 Heads on my LS2, going with a BTR Stage 3 and I want to make sure it will clear.

If they will clear how far can I mill the heads and get away without flycutting.

Cam Specs are

229/244 .615"/.595" 113+4

That's going to be fairly tight as is, wouldn't want to mill much if at all.

Hard to tell what your PTV is without measuring. Also, headgasket thickness matters so that needs to be part of the conversation also.

If the block and heads have NOT been cut, you should be fine.

That having been said......I would go to the source and get Brian's take on it.
