I am looking at a set of 5.3 heads but i just found out that they are milled .015. I was wondering if the X3 will clear even with this small amount of milling.

The X3 will not fit with un-milled heads. You need new pistons or a fly cut to run that cam 'safely'.
LG said to fly cut .060 with un-milled heads, so you would need .075 to clear!

I believe the 5.3's should have same clearance if unmilled, the problem come once you get into larger valves I believe. I think you would probably have to flycut, but no one will be able to give you a definate answer, youll just have to check and see if thats what you want to run. Whatever you do, dont just hope that it works cause someone said it would.

My 5.3's are milled 0.030, and it took a pretty deep flycut - 080 or more to clear my G5X3 on 112 lsa with 2.04 valves. The big problem is the larger valve size, especially on a 112 lsa. Stock size valves on a 114 lsa are supposed to clear, any other combo requires a flycut. I'd call Lou to be sure how much.

under_construction,
What problems would cutting the pistions that much cause? The reason I ask is because I have the same heads cut .025. I have a FM13 114+4 going in and if the shop tells me they have to cut for it I think I am going to step up to a G5X3 112 and have them cut a little more.
