Default Best head gaskets??

Looking for opinions on the best head gasket for a boosted application. Iron GMPP LSx block with aluminum heads. Used a receiver groove SMC gasket first time around and had water get in 3 holes just sitting - no boost. Thinking of switching to a MLS type gasket like Cometic or the MLX gaskets. Looking for real world opinions. Thx

A lot of people like the ls9's.

Some use felpro mls gaskets.

I've only ever used cometics.

They are probably all just as good. I've seen lots of times head gaskets get a bad wrap from a jacked tune.

Ran Cometics on my 347ci on 11#s ARP studs and never had a problem. Went with LS9's for my 383ci with the same ARP studs and 9#'s no problems either.
