    Tomorrow I'm going to re-torque the long head bolts and hopefully i'll be able to get something on them and if not i'll have to get something sorted out and get the heads magnafluxed i guess.
    The torque on those ARP head bolts are like 70 or 75 ftlbs iirc. Torquing them more isn't going to compensate for a crack.

      I had originally torqued the long bolts down to 75 with the moly paste they supplied and I was hoping to see that they loosened a little after heat cycles but no dice, all clicked at 75 lbs still so the heads are comming off in 2 weeks, and while i'm at it I might try my luck with the comp xe-258 cam and some new valve springs.
      Finally have an on the books porting/custom fab business!

              yeh new heads, I've had enough screwing around swapping head gaskets and doing rebuilds trying to find the problem which is probly a crack so i'm buying a set from promar engine so i'm guarenteed a great set of problem free heads to slap on. Could be the current "P" heads just need re-surfacing even though they checked out fine for warpage, or a small crack repair...if a shop can make them check out i'll sell em I guess with my 1.7 RR's.

              I have seen enough hype about this 258XE cam so I guess someone's gotta see how it works or fits with the PTV clearances... So i'm going to give it a whirl.
