In prepping/warming up the motor on my Alfetta GT for the next race event I noticed I was getting air bubbles through the radiator cap (22lb) into the overflow bottle, (not a good sign) so I'm pulling my head and replacing the head gasket suspecting it's leaking at one of the cylinders into the water jacket area in the block.

Seems like I'm only getting about 2 events on my head gaskets and am looking for advice on right type of head gasket, intall tips,etc. the motor is not supe high copression, maybe 10 1/2 or 11 to 1, has an o-ringed head with fairly fresh valve job. hot compression tonight was 210 across all cylinders except for #3 that was 195-200 hot.

Also intested in what is recommened for lube on the head bolt threads and torque procedures and setting that other use successfully.

Thanks.

Spesso racing , Navalinea, Reinz , Goetze , Elring are good gaskets !
check liner protrusion they must sit 0.06mm higher than block ! O ringed head with stock gasket ? show some pics of ringed head? ... usualy o rings do not work with stock type gasket!

Ditto TS's comments. Never ran an o-ringed head...but would think you would need a different HG. Short of his comments....if you are using a quality HG like a Reinz....then I'd be checking my head. Compression numbers you quoted are not the issue.

I ran my gtv20l turbo with "o" ringed HEADS. No problems,worked very well..So did "o" ringed liners,and it was easier and cheaper than doing the heads..

Which is o-ringed? The head or the liners? I run o-ringed liners with stock type headgaskets and haven't had any problems. I can't remember which one it is. But one of the available headgaskets has a much wider "fire ring" that might seal on the o-ring better. But again, several different kinds have worked fine for me.

I do lube the nuts with moly lube and torque to 68-70 pounds. I believe the book says 60 pounds.

If directed at me,I did both the head at some stage as well as the liners later on..Both methods worked very well,liners were much cheaper and easier to "o" ring though..
