CB750 Head Gasket copper or not ?

<< < (3/3)

H2Eric:
Dynoman in the USA has a whole range of copper gaskets, check out the SOHC page on the web site http://www.dynoman.net/bikepages/sohc/index.html

I use a copper gasket on my 998cc engine - billet JMR block with nikasil bores and a thin wire 'O' ring fitted around the top of each bore. A quick spray over with 'Copper Spay-a-Gasket' helps to seal the whole caboodle.
My CR750 also has a copper gasket fitted, no leaks there either.

This guy appears to have one or two copper head gaskets.  https://www.ebay.co.uk/itm/HONDA-CB750-COPPER-HEAD-GASKET-042-THICK-X-61MM-BORE/311395399538?hash=item48809cb772:g:fPUAAOSwu4BVlsXC

I am going g to use a copper head gasket on one of my engines, I had one made a bit thicker into compensate the head been skimmed too much, I intend to use hylomar spray to seal it , having googled it that seems the way to go, does anyone see any problems, it's a 69, 750 head too expensive to waste so this is my option to salvage a very expensive head
