PTVC on my 6.0 build

Okay trying to get everything together to assembly my new setup and I am worrying about valve contact thought I would see if anybody thought it would work out without having to order pistons as I am just not real fond of the flycutting idea. I already have a set of .041 mls gaskets but am not against running the thicker .050 I would much rather have the higher 11.5ish compression. Hopefully someone can do some math and see if I have room for this to work.

Short block is 03 6.0 with 16k on the clock "10cc full dish LQ4"

Cam is a comp grind 236/242 .597-.607 on a 112 lsa

Heads are 5.3 862 castings have been seriously ported and polished, at the shop right now getting a valve job and some hand me down freebie 2.00 intake valves installed, sporting a set of Isky .650 springs, never been milled so they are stock 61.15cc

Only 1 good advice: Mock assemble and measure, too many variables.
BTW the gaskets are .041 (not .0041)

In the process of pulling the old engine now to get all my internal ARP bolts out so I should be able to mock up and check clearances in a few days. Just found out that one of my buddies does have a flycutting tool and a head to run it in so worst case scenario if slight contact I will put it under the knife.

Good news finally got the short block together today and done some clay on the pistons. Welded me up to solid lifters and bolted the heads on. To my surprise I no contact, I was really starting to get worried about it till today. Looks like I wouldn't have had room for either another degree of duration or any lift at all. I don't know what the recommended clearance is but looks like I may have .028-.030. I am gonna let the clay dry and break it and actually mic the section where the valve was coming in. Needless to say it didn't make contact and I am going together with it.
