Thread: MLS Head Gasket Difference

A friend is building a new motor and we're trying to figure out the pricing on ZZP's MLS Gaskets...

.045" = $155...3-layer
.051" = $155...3-layer
.052" = $165...4-layer
.060" = $175...5-layer?
.065" = $165...4-layer
.066" = $185...6-layer?
.074" = $175...5-layer?

Also, for a T67 turbo application pushing about 15psi on a L67 bottom end, what thickness would you recommend?

Any help would be appreciated, thanks.

On what fuel?

.065 4 layer would suffice. The problem is that a stock gasket would probably hold on 15psi depending on the afr/fuel type/timing. Saying flat out that you're never going over 15psi on a t67 on such fuel and such timing you would probably want to go with a shorter thickness.

93 pump gas.

I said "about" 15psi, lol. Im sure Ill go higher.

Zoomer said .060" would be best.

have fun sealing them, or so i hear.

Copper spray is my friend.
