Edelbrock Cylinder Head Quality

We just followed that advice and here is what was found on our 63 cc Edelbrock heads:
- A couple of guides a bit tight due to small burrs left from the guide machining process
- All the intake valve seat contact points were incorrect and were fixed with light re-machining
- There were a few valve seats not quite concentric with the guides.

All this was easily corrected with a little bit of work on the seats and guides. Cost was around $100 at one of our local shops on a Serdi valve machine. (NOT the shop that messed up our block decking!)

We did some basic checks ourselves and found all the valve heights to be very consistent (+/-.002" across all valves on a given head), and found the installed spring heights to be on spec. Shims were installed on all springs. Rocker bolt hole and rocker fit was consistent; the threaded inserts were a bit deep but OK.
