90 over 318 Head Gasket info needed !!

I have been meaning to ask what's going on top of that build. Looks like a good foundation for a W2 econo setup.
Good assumption but we are not allowed any off set rockers so to be legal I cant run them - and must be stock valve angle !!!
I have some new rpm 340 heads and had them ported in middle GA @ Killians and we are also not allowed any air gap intakes so kinda limited ### Of course I had to order a new port o sonic from OFFY last week
It was one of the best if not the best single plane single 4 set ups of its time / once its in I will take it down and have it ported etc.
