    06 RXP Blown Head Gasket

    I need some advice . I have a blown head gasket for the third time.The first time the stock one and the other two the R/R high performance gasket. I am running a full stage 3 with a 159 thermo and Block guard. i had the head rectified and tork to 85LBS also have the head studs from R/R. Running 12PSI Boost.

    If you go back with new stock stretch bolts on the head they are torque to yield bolts. They should be torqued in sequence to 30 ft lbs first, then 120 degrees and then an additional 90 degrees using a torque angle gauge. You should not have a problem if done properly. I can't say regarding the RR studs, but 85 ft lbs on studs would seem to result in way less clamping force than the stretch bolt route.

    The RR gasket is a stock gasket with one layer removed... it's going to be even more prone to leaks.

    Insandiego just got the Riva head gasket and was highly impressed. Obviously your compression will be closer to stock, since it appears to be stock thickness.

    You REALLY need to have your head and deck rechecked for flatness...

    You need a fresh one. I went through the same thing. I used the Riva head gasket, stayed with the ARP studs and torqued as recomended with molly lube and went to final of 85, in the sequence 20, 40, 60, 85. I also went open cooling, not sure if that helped with the problem. So far all is good.
