I've been browsing for some time while putting my '90 ka-t together and have my first real question. I've been searching for a couple of days, but have no real answer yet on this. I am trying to find a more performance oriented head gasket for my sohc ka-t project. I have stock internals on all fresh machine work for the head and block. I am using the CXracing turbo kit which seems o be working fine at this point. I started engine up after build held rev at 2500rpm per builder's guide to seating the new rings correctly. I took the car up on the highway for a total of 2 miles, never running it hard. boost is set low at 7psi, but feels extremely smooth in operation. The issue is this, after all of 33 miles on the build, I took the car up to 5000rpm in 3rd gear 1 time, and at the end of this short pull I had a stuttering engine, and the tell tale cloud of white smoke so thick that the road behind me could not be seen. It smoked like this for the 1/2 ile ride home (watching the temp gauge the whole time), and used up all the coolant. I first checked compression which was solid a 155 on 3 cylinders, but only 120psi on #3. I added coolant, and cranked engine with no plugs in it, and of course out shot coolant from plug 3's home. I have not yet pulled it apart, but I guessing this is either a gasket blowout, or crack in head. It is held with ARP studs torqued at 70, so I don't think that is the issue. If there is a better gasket out there can someone please point me in the right direcrtion. I have already read about the mod of the dohc cometic but I'd rather have something made for this engine.
