Hi Brad,
Not sure you got my private response, so I'll respond here. Found some
treasure in Eastern Mass? I'm all ears!

Is Brian or anyone else in Eastern Mass' out there? Drop me an off-line
message if you would - I may have something interesting for you to go
take a look at.

Subject: [alfa] Valve Shim Minimum Thickness
Hi all,
How thin can the valve shims go? I'm in the process of reassembling my 1600
head after having the valve seats and the valves ground (new guides and
resurface also). The work was done at an experienced alfa shop. The seats
were
cut/ground with a 3 angles and did not go below the chamber surface. And I
don't think much material was taken off the intake valves (maybe should have
just gone with new ones!). The exhaust cam went in with shim thickness
within
normal range (.060 to .080). On the intake side the shims are on the thin
side
with one shim calculated to be around 0.042", less than what's available.
The
cam is a 10548 euro cam. Looking at what available for minimum shim
thickness
is see 1.5mm (0.059") as the minimum list (two major US suppliers).
Does anyone have experience with going "under size" on the shims. At some
point I guess the shim may end up failing/crack? Also grinding the shim down
would need to keep the surfaces parallel and the question of hardness would
need to be considered. Can the shims be annealed (heated cherry red with a
slow cool) and then after grinding re-hardened (heat cherry red with a
quench). Anyone know the Rockwell hardness on these?
I've put the head on the block with the new head gasket but have only
torqued
the nuts to 15 ft-lbs (BTW - I found my lost nut). If I need to remove the
head and put new valves in how bad would it be to try and reuse the gasket?
Thanks and Happy Roads,
Al
