I am debating on O-ringing my CR block with my Isky O-ring tool and wanted to see what you guys run for wire protrusion with the MLS gaskets. I use the thicker MLS gasket, I believe its .015" thicker.

I use .035 wire and usually run a .015" wire protrusion but that was on 24v/12v gaskets, I didnt know if it should be different on a MLS gasket.

I dont have time for fire rings as I am in a rush, need to have it done by tomorrow evening. So its either O-ring the block or leave it alone and just install a new gasket.

I appreciate any advice!:Cheer:

Torque the head bolts tighter and run it.

I went to 140ft lbs this last time on my ole ARP 2000s. :evil

Moar?

I just rebuilt the head, so it should be in good shape. Nice and flat.

Yea, my new motor has fire rings and 14mm head studs, I just wanted to try and get this one to last a little longer.

An out? I have had better results with head bolts, that's the gist of it.

I run stock bolts torqued to 120ft lbs on my 04 with a small tow twins set and stock fuel, knock on wood (as I am about to drag 20k lbs across 3 states) I havent had a problem in 200k miles.

This truck makes almost 3 times as much HP though.:rockwoot:
 
Phillip Franklin brought something up I never thought about on the MLS gaskets, they aren’t round... so it makes since that O-ringing would be less than ideal for that style gasket.

I'd leave er. Good and flat goes a long way. And step up to 625's.
