you use 3m heavy duty scotch pad and hand clean the deck... till its clear and clear aluminum, no power tools (*takes some elbow grease)

once its clean, you blow it all off (get the stuff that fell in the cylinders out,

then you take Permatex 80697 Copper Spray

you spray the deck, and the top of the motor (dont put rags in the cylinders) what ever is on the top of the pistons will burn off instantly

you spray it pretty good... coat it well.. but not to the point where its running or liquidity or collecting

the objective is to make up for the few thousandths of variance that occur when the cylinder head is removed from the block

so spray moderately, immediately set your head gasket in place and then repeat spray again (same as the first time.. just the top of the head gasket)

let it setup for about 90 seconds or so.. and then place your head on and torque


*this has been the method that i have used (*which i was shown by a airforce guy) for dozens of motors.. I have never had to redo a head gasket or had a head gasket go bad after ive done it..

the only exception is if the block is sent out and decked.. you dont need to do any of that.. you can just mate the head to the block with the gasket only (*honeslty even with decking the block... Id do it)

This is a good 2nd step to try if I still get vapors after tightening the head bolts a bit. Anything beats having to re-pull the motor, although I shudder to think of the work required to pull the exhaust manifolds off the heads while in the engine bay..

I suppose I'll have to buy new head bolts, cam bolts and a new head gasket as well, since the bolts have been torqued to yield.

I think my 540 is gonna divorce me if I keep putting too much effort into this 545, lol

I know you don't here this a lot, but I have to admit you are one of the most knowledgeable guys here. I love to read your tips. You have jumped on me a couple times, but I am a toddler compared to the wealth of info you release so freely!

If judged by my use of the written English language: (*which i spell on like a 2nd or 3rd grade level)

i would be and often am called all sorts of words.. BUT ive learned thru life, and sometimes at the expense of others that its better to let your actions speak and let the lack of sound confuse the mind of the non intrigued

and I must admit, getting back in to karate HAs been THE SINGLE best thing ive ever done for my self:
