[Supras] MHG's

[Joel Watkinson (Cars)]

So, I'm looking to install some NA cams in 7MGTE. I assume it would be a
smart idea to go ahead and refinish the cam caps when I do this. What's
involved in refinishing that cam caps? Does anyone know a of a shop in
the DC area they'd trust to do the work or is it better to ship them
out? Or does the work need to be done on the head and the caps?

Thanks,
Joel
'87T still have it - still not moving - still buying more parts for it
