head resurfacing

Post by ride dont hide »



Hi Guys, new to the forum, seems like a lot of GOOD info here so had to join. Doing my first head gasket replacement and wondering how much metal can I safely remove from the head to get rid of a few scratches on the sealing surface? Some say install gaskets dry some use copper-coat. Whatcha think?

I would install dry. I have installed dry and never had a problem. As far as how much you can remove you would need the specs and have it measured. The head service limit is 0.10mm or 0.004 in . That is the factory spec.
Thanks to all who answer and help. It is greatly appreciated!

Tack glue a piece of 100 grit metal sandpaper to a mirror, place mirror on a level surface, place head on sandpaper, and use this to remove scratches from the head surface. There is a DIY on this site for just such a problem. Just sand lightly with equal pressure and there shouldn't be any worries about removing to much aluminum. Let us know how it goes. Regards, Johnny

Two great answers, thanks again. I did install dry with no problems and also used emery sheet on a flat machinists block. That cleaned up the heads really well after my local machinist friend checked for any warp. The Franken-Wing is on the road again!
