Hey all,

I'm looking at buying an e34 with the M30 big six. One thing that concerns me is the owner says the car overheated and he replaced the head gasket and all engine cooling related components. He also said the head has been decked, but did not know how much.

Is there anything I need to be concerned about with regards to the head decking? Will valve adjusments be different now? Any advice much appreciated.

Thanks,
John
p.s. even though this is an e34, I have found the e28 guys are more technically informed on the M30 engine.
