3 angle valve seats...

[Gerard <gerard@poboxes.com>]

Hi!

I'm off into a bit of a panic here to get my cylinder head
reconditioned on the 1990 200 with MC motor. I just got off the
phone with one of the biggest local performance shops and they
quoted me some R4400 ($730) for a complete recondition and
gas flow of the cylinder head. This includes parts (seals,
stems, no lifters), gas flowing and a 3-angle valve seat job.

Question: what is the effect of this 3-angle seat job?
Benefits on a turbo motor?

Does the pricing seem justified?

I was planning to do a simple recon and have a friend do the
flowing. The local Ferrari engineering works here in Cape Town
quoted me R750 (about $125) for reconditioning without parts
or flowing.
