2.0L heads... Help

rjm · 01-30-2002, 07:56 PM

Last year I had my '75 2.0L heads rebuilt by Mark Stephens (mistake 1). They convinced me that stainless steel exhaust valves were "just a good as sodium valves" well I bought the line (mistake 2). Now comes the problem... apparently #3 exhaust valve got a little tight for the valve guide and the guide broke loose from the head. I don't think the valve is actually seized, I can't tell for sure yet, the head is still on the car...but looking though the intake and exhaust valve springs the exhaust guide is clearly sticking out farther...
My question is, is there a good shop in the Berkeley or San Rafael area that can do a good job replacing the one failed guide and install four sodium filled valves?

Don't know about NOCAL, but in SOCAL I would suggest Rimco.

This thread got me interested in looking up some references on sodium-filled valves and I found this site:

http://www.peebles34.freeserve.co.uk/Pages/Big%204/THE%20BIG%204.htm#va

I've never seen it before, but it's got a lot of great info on T4 applications. Crummy page design, though - make sure you click on the "i"'s to see hidden info.

Regardless, it has some of the best explanations and pictures of valve problems that I've seen anywhere.

Tech Craft in either San Mateo or Redwood City. (I forget exactly how far up the Peninsula they are). They're pretty good; Bontempi from High Performance House told me he uses them for his street motors. They're right next to Elgin Cams, and used to be associated with each other long ago.

I don't know if they do welding on the heads or not, so it's possible you'll wind up SOL if they're cracked.

We are running out of good 2.0 heads. You would really be suprised just how much work we do to 2.0 heads to get them right. Weld cracks, re-do spark plug holes, install new guides and we make our own seats and use induction hardened valves and seats for the unleaded gas we burn.. We even weld up blown heads and reprofile the combustion chamber to stock specifications. OTTO
