[Healeys] Head Gasket

[Michael MacLean]

Even if I figure out which way to put the head gasket on there still is a few more questions.  The service manual says to torque the head bolts from 65 - 70 ft lbs.  It does not mention anything about the rocker studs.  I'm guessing they are torqued to the same specs?  As far as coating the gasket I intend to use Wellseal.  And my head was also previously repaired between 2 and 3 by an old school welder.  The problem was to repair the crack needed a lot of meat ground away from the intake ports of 2 and 3 to do the welding on the inside of the head.  Of coarse the head would still work, but I just thought the air flow would be different between the inner and out intake ports.  I had the head pocket ported to even the flow out some.  Who knows, it may all be for nothing if it cracks again.  Then I'll spring for an aluminum head.  At least then I will have this gasket and torque thing pretty well sorted out.Mike MacLean

I think the proper torque of the bolts on clean studs, in the correct order, is the most important thing you can do to insure it does not leak. Cracking is another story-DO NOT LET IT OVER HEAT.
I had my head repaired by Midwest Heads and (knock on wood) its still working properly. It had the usual crack between 2-3 from overheating at some time in its life. Both the block and head were planed as well. Hank, healeyhelper.com

Not trying to cause any confusion on this topic. The reason the Payen gasket is marked TOP and FRONT is because the gasket WILL fit either way. The lower photo is two gaskets, one atop the other but one is TOP up and the other inverted. The holes all line up.
The issue is which side of the gasket had the cylinder crimp, the bent over seal around each cylinder, is up or down. On older copper faced Payen gaskets the crimp is against the block or Down. Thus the other side is marked with the Top and Front markings. Some later Payen head gaskets use a one piece (separate piece of metal) crimp. After this change the gasket I have looked at are not marked Top or Front.
