So if I when from the motorsprots gasket to a .027 gasket how much volume would that decrease. Still wanting to put the new heads on with out losing to much compression

We bought an A-460 block and it looks like they copper o ringed the cylinders. Can you use a cometic head gasket to get a good seal without having the block decked? Seems like nothing is ever easy, oh, but, that is racing isn't it?

Lem Evans November 29th 2011, 10:11 am

The block grooves will have to be filled or milled off.

Would JB Weld work for that?? What is the price for a pair of 4.465 bore, .051 thickness cometics?

Thanks

Might actually work...... scratch

alot of epoxy's are good for 700 degrees......

Curt November 29th 2011, 2:05 pm

Actually I have repaird a Cadillac HT4100 block with it, but there is an easy enough fix with wire and a mill that would allow the deck surface to be properly surfaced for the cometics. IMHO

dfree383 November 29th 2011, 2:22 pm

I argee thats a good way of doing it, but their could be other was as well.

Lem Evans December 19th 2011, 10:26 am
