Default 83mm LS headgasket so hard to find..

Seems like not many people have ran this set up but i am having the hardest time finding a straight LS gasket in 83mm, i even started considering using a b20 headgasket but the heads are different LS and b20 heads have different coolant holes around the cylinders... there was 3 companies that i know of that make a straight LS 83mm head gasket, one is cometic i use that and it started leaking right away(not using cometic again), second option was supertech their gasket came in today and had some issues with the gasket blocking a few coolant holes, my only other option now is JEproseal..

does anyone else have any other options that i can use? seems like 95% of people that go for big power on 83mm bore run vtec heads.

here is a video for you guys to watch..

Cometic historically makes a quality product... maybe the problem is not the gasket. Also, a few coolant holes being mis-aligned or covered is not a huge deal, and if you really feel that they are in fact necessary, you could trace the missing holes from an OE gasket to the new gasket and then drill them on a press slowly with the gasket placed over a piece of wood so as not to distort it.
