I'm selling 2 pairs of TA Performance Copper Head Gaskets. Both pairs are .040 thick. I had used them in my engines that had been O-Ringed. One pair are stamped to fit the Stage 2/ fifth head studs, though they can be used on Stage-1 or Stock heads when you need a gasket for Ultra High Compression. The other pair are the same less the 5th head stud holes, though they can easily be stamped for the extra studs. They are used but are Super Clean and only need to be re-annealed to use them again. These gaskets sell for $230.00 per pair new. I am asking $100.00 per pair or $180.00 for both pairs, plus shipping. Larry
