I am in the middle of a complete rebuild (
http://www.toyota-supra.info/forums/...e-rebuild.html)
and have been researching Head Gaskets. I bought a rebuild kit for $200 and decided to throw away the included HG because it was junk!
No crush rings on the water jacket ports and looked like it going to fall apart on its own. I have found a OEM style HG at CARQUEST and NAPA for about $75 that has the OEM crush rings. Also found some metal HG at
http://www.jscspeed.com/mk3/engine/headgaskets.htm which run about $140.
And don't forget should use new Head Bolts at $100/set
Here is my opinion - all the work to teardown and redo a HG is hours of effort and money. Why waste all that just to save $20-$40. If you are doing the HG you might as well do the timming Belts and have the valves done which is going to cost $400 to $600 anyway. Not to mention the OIL, COOLANT, PLUGS, HOSES and more. And forgot to add in HEAD BOLTS at $100
Buy the best HD you can find and save the worry on doing it again in a few monts
