Anyone using an MLS head gasket on a turbo/blower combo up to around 30psi?
Have they worked out for you? Please state your block and head material.
I'm thinking of trying some on my small 4.090" bore turbo combo rather than getting the heads and block cut for o rings and copper gaskets.
They seem to work ok on the SBF with the small bore and 4 head bolts per cylinder.

Not boosted, but in our case with John's IA2 block noted below in my signature its a 13:1 nitrous application. Dry deck and reverse cooled. The custom Cometic MLS gasket has no cooling holes in it. No issues.

Thanks for the info Steve, I have already emailed Cometic asking if they can make me an MLS head gasket without the coolant holes, what did yours cost? I would think that it wouldn't be a problem to just delete the coolant hole cutting process when they make a gasket.
ps,mine is dry decked and reverse cooled too.

mid 20s on the boost the Cometic gasket lasted for a while, but finally gave it up between center 2 cylinders -- I ended up going to copper and o ring -- 4.250 bore

I used Copper and o ring/receiver groove on the previous block without any problems, trying to avoid the time and cost on this block, I think that maybe with my small bore (and iron heads) the MLS would work.
