I would have the heads o-ringed

I was also under the impression that you had to grove the block as well to accept the o-rings. That's the part I was afraid of.

have a machinist o-ring the heads..not a do-it -yourself thing

So you can o-ring the heads and not have to worry about the block?

RE: Head Gaskets...
TTT I really want to know the answer to that question too.
Also, I guess Im just going to wait and get heads now before I install my u/l manifold, tb, vc's, etc. Geeze........ just MORE waiting! LOL

RE: Head Gaskets...
Ohhhh Ok. Thanks 2kwik. Also, is it worth it to have the heads o ringed if you are just going to have them done and not the block? I will be running approx. 10 psi with my setup I am working on and I just want it to be realiable but to be totally honest, Im really not trying to have the block o ringed.

RE: Head Gaskets...
It's not so much the head gaskets, but rather the tune. Specifically, A/F ratio.
Most of the aftermarket head gaskets will work and is certainly a good replacement over stock. One of the differences is compressed thickness that has an impact on final compression ratio. So consider this in your combo. The head gasket is your fuse. Muli-layer, copper and o-ringed gaskets will certainly hold up "longer" to detonation, but if the tune is off they too will let go or other rotating parts. I've seen bent rods and broken pistons with head gaskets intact. Keep your A/F in check.

RE: Head Gaskets...
if the block isn't machined to accept the o ring and the compression force needed to seat/seal the o ring, how does it work? is this similar to piston rings on cylinder walls? i assume it is, but we use alot of o rings at work for medical devices and all our metal parts that use o rings have seating/compression tolerances designed into them, that may be just for a factor of safety though. Thanks in advance.
