Title: ADVICE NEEDED E30 M42 Head
Post by: Ex-m20_owner on July 12, 2008, 08:52:41 AM

Im building a E30 m42 head  but I would appreciate any suggestions, in a mild built head. I am going to use the vw lifters I found the part number for them.  I wanted to know about using the 6MM valves from the E36 m42... are they a direct swap with the 6MM valve guides? I know the valves are the same size but is the length the same? also what other parts would I need. are the valve keepers different? any one help ?

AFAIK, everything is the same. You can verify the keepers and retainers by going to realoem.com.
Do you have a e36 head to pull parts from?
Why not just rebuild it instead?
Valves are expensive.
The VW lifters work well.

The VW lifters are hydraulic = no clearance

This thread is old!!!

I'm interseted in this subject.6MM E36 valves in E30 head with vw light lifters.
With good oil pump I should be good to shift @ 7K.

Yes you can use the 6mm valves in the E30 head as long as you of course use new 6mm valve guides:) They are all the same from the S50/S52 M3 and M50's.
