Milled 243 heads and MS4??
Milled 243 heads and MS4?? Hey guys,
First off i have a stock 02 ls1 with the MS4 cam, and supporting mods of course.. and i there are some ls2 243 heads for sale locally, but they are milled .03. The seller said they should work, but would get a thicker head gasket to make sure for clearance. Can anyone answer the question? If so all i need a thicker head gasket, any particular brand and size? If so im getting the heads ported and calling it a day.
Thanks for any help/suggestions.

Yes and no....the thicker head gasket would work, but it's like giving that guy from Florida a 2" non stick bandage for his face that's missing....all you would be doing is making lower compression and getting your quench too large which would promote detonation....if your getting a desk on the heads pick up a set of .040" MLS gaskets, then measure your ptv and have your pistons fly cut to fit the cam. It will cost a little more but will be worth it in the end and will be done right

Thanks guys, i just didn't know how much can be milled for it to come into clearance issues. I don't want to fly cut, so looks like im going to get the TSP stage 1 ls6 243 heads.

That is just a marketing gimmick. Nothing but wrong geometry will result from that. All this is a way to convince novices that their cam is the one to buy. Same BS as putting 2.04 valves on a 2.02 seat and advertising those heads are the bomb.
