will this run on pump gas ?

If I can get the RHS heads to 68cc and go with the next cam up that will get me to 8.5:1 static

INT/EXH - Dur @ .050” Lift: 227°/237° RR: 1.5/1.5 Gross Lift: .480”/.503” LSA: 112° RPM: 1800 to 6000 Redline: 6500

Cometic has a head gasket with a 4.040 bore that is .060" but they are $123ea

Or I can just do some LA heads. This is also all assuming the 107s are at zero deck
