Headgasket choices and recommendations

[boostedmklll]

I have a 90 supra with 115000 miles. Stock block and head. 57trim ct26 greddy front mount with 3" hard piping. 3"downpipe and 4" exhaust. Lexus afm rc 560cc injectors. I recently started seeing smoke out the exhaust. Did a compression test and cylinder 6 is barely 100psi. Going to get head decked and do the head gasket with arp studs. Just wanted some recommendations on what head gasket to run. The car is an scca autocross car and gets driven hard. Currently running 14psi. Thanks for your help everyone.

If there is a stock hg on it and your not machining the block run a stock head gasket.

It has a hks metal head gasket now with arp bolts. Im machining the head but not the block.

Then as long as the block is clean and straight mhg should seal.

Doesn't matter which one you use they all work.

Ok. Just was not sure if there were any that hold better than others

The hks stopper is the best. Bit pricey tho. All the others are pretty close to the same.
