Fel-Pro Head gasket 8347PT 1 or 1013 or ???

I purchased the Fel-Pro gasket set for my new build and it came with the 8347PT 1 head gaskets. I was going to buy the 1013's, but if these are good gaskets I'll use them and save $80.

I did a search and it's unclear if the 8347's compress to .047 or .041. Does anyone know for sure or should I call Fel-Pro?

My pistons are in the hole .025. A .72 quench seems really big and I read may cause performance issues.

Thanks.
