Supertech Valve guide problem
I'm having a problem with my Supertech Valve Guides....

I ordered and received GDE-NSR6-I and GDE-NSR6-E

My machine shop have told me they are too thin and dropping out of head.
I had them measure standard guides and Supertech guides and there is a slight
difference however slight but still enough to not sit tightly.
It is a standard sr16ve head....

Standard: .395 inches = 10.03300 mm
Supertech: .394 inches = 10.0076 mm (advertised as 10.03300 mm)

Has anyone had this problem before?

Supertech contacted me back and are sending me new ones.....

This is what they said.....
Some months ago we had a batch of some Exhaust guides that were a little
small in diameter.
We will replace those guides

Let us have you address and we will send the replacements.

POC this is the pain in asking questions on this fourm. very few if any do things different. Next time post it in the VVL section someone might have ran those before.
