Head gasket install question

[deion82]

My new head gasket's are not labeled. Do the water holes go to the front or back. I don't remember but i'm thinking the front. Does it matter which gasket get's flipped so they are both the same way. Also do any of the head bolts go into the water jacket so I can put sealant on them.

most HG's have "front" on them. upside down or not, it has to be in the front.

Top bolts use oil or moly lube, bottom bolts need teflon thread sealer since they penatrate the water jackets.

What gasket are you using, never seen them not marked.

I put sealant on all of mine and the water holes go towards the front!

My head gasket's are mr gasket ultra seal. huh!! one guy told me the hole goes to the back. He said the water flows through the block from the pump up to the intake then back front to the water neck to the radiator.
Thanks for the info.

Skip, your's are on wrong... coolant passages to the back on head gaskets...

Coolant flows from the bottom radiator hose to the water pump, through the block front to rear, up through the holes in the gaskets and back out through the heads, finally up through the front of the intake to the T stat and upper hose. The extra holes in the gasket keep local steam bubbles from forming under the gasket.

With them in wrong you will have overheating problems in the rear cylinders.
