what all is involved in using the chevy SS valves?
JimC posted the valve sizes (somewhere on MUD) which I used when ordering a set from a local valve source here in Utah.
Then had my machinist install them
I understand JimC does (did) head overhauls doing the SS valves.
One of the SEV or POL is no longer available, the other one is the ordered
My machinist found seals that fit, the 2F seals did NOT fit. He also
found some springs that fit
1.5 inch Exhaust
1.84 inch Intake
Here are some emails:

I don't remember what the difference is. Call and ask 'em which would be better for a low RPM torker engine.

Doug,
Plugs are all $1 ea, plus $5 to put them in a priority Mail box to
you, so $11 for what you need.
The SBC valves are standard length 1.84 and 1.50.
I like these:

Use the short springs from exhaust valves on smog SBC. And standard
retainers and locks. and whatever seals will fit. IIRC, we're using
ones spec'ed for ford V6??
