How to o-ring a block using ISKY's Groov-Matic O-Ringing tool.


most machine shops charge over $200 to machine a block for o-rings that help prevent head gasket leak issues that are more common with use of super chargers or NITROUS, you could buy the tool linked here to do the work yourself but if your not experienced have a qualified machine shop do the work rather than potentially ruin your block.
$340

now I have to point out I've used solid copper head gaskets that are sold , and (designed to be used with those o-rings )
( yes I've been using those solid copper head gaskets without using the O-rings)
for 4 decades and have yet to have a head gasket leak
