What heads? 6.0L, 5.7L, 5.3L, and 4.8L.. We can answer your question better if we knew that information..

That would be pushing it.. I do not think you would need to mill them that much.. I would shoot for 10.8:1 personally.

You will definately want to check with Thunder first before milling those heads at all. The clearance for that cam on stock heads is very tight, and they aren't even sure that any milling can be done safely without fly cutting the pistons. Check with thunder before doing anything. When I ordered this cam 3 weeks ago, they were not very confident that there would be much room for milling, however they are checking very soon on clearance with this cam..
