Mitsu MLS Gasket, to seal or not to seal......

[Thomas91169]

Ive searched around and it seems that everyone has mixed feelings.

I will be installing a Mitsu MLS gasket with ARP studs on a freshly resurfaced head. the block however will not be resurfaced but i will clean the mating surface as much as possible.

Should i use a copper spray-on sealer or not?

I say use it. Make sure you spray it all over everything, the pistons, the valves, make sure you get some on the cams as well, just to be safe.

Please note that he's being sarcastic here. If you want my opinion I'd hand lap the block, spray the gasket and install. We've been over this before though
