PTV Clearance - Pushing the Limits??

PTV Clearance - Pushing the Limits??
Im in the process of building my motor and am going with about 11.4:1 compression. I just need to make sure that I will not be running into any issues with PTV clearance.
Specs of my motor:
Stock deck height (.015")
Mr. Gasket .026" compressed height head gaskets
Speed Pro 4.030" Forged Pistons with stock style 4 valve reliefs (+6.10cc)
Milled heads down by .020"
The cam I am using is a custom grind by L.E. 234/238 .565"/.565" on a 112 LSA
So will I be screwed by having the heads milled?

You should be ok but you need to check anyway. I don't think the .020" off the heads is going to be a problem. I used a cam slightly smaller than that and .039" head gaskets and had about .250" PTV. I didn't measure exactly since I had so much clay left.

+6.10cc would tend to tell me these are domed pistons to raise the comp.
