Re: ARP standard vs. OEM 6 bolt

So what do you guys think about a composite gasket? I'm not really sold on the MLS ones, seems like many have coolant pushing issues, probably cause everyone else is cheap like me and doesn't want to yank the block to have it machined. I'm aiming for a max of 500hp at DB. Whats the best composite gasket? OEM mitsubishi or a fel-pro 1153?

If you are stuck on getting a composite, I would vote Mitsu. If you want to do it once and never fuck with it again, A1/L19 and FelPro Permatorque is the only way to go.
