well i bought a uad about 2 months ago with stage 3 hot cams... ported and polished head... and 13:1 416 piston... about two weeks ago i was gona go to a track and noticed my head gasket was blown... so i went up and bought the strong metal gasket and put it all back together and rode it about 10 times then yesterday i noticed its blown again.. i was reading on here that 9-10 its your head studs... gt thunder web site says they pull out from running hot and not runnin high octane fuel.. and mine does run really hot and i run 93 in it witch i should run higher.. but im just tryin to figure out wat could be blown them this quick...

Get the studs...I dont know why the 416 is blowing it, but the 440 is known to do it.
13:1 and pump gas may have something to do with it, but i am definately not a engine genius. I hear 11:1 and pump is highest you can go tho.

the size of the bore isnt the problem. its the compression really.
