3 angle grind and +1mm over on both intake and exhaust valves. New bronze valve guides. Light porting.
Around .050" or .060" shaved.
Comes with +1 over Kibblewhite intake valves. You'll need to supply the exhaust valves.
I ended up shaving too much off to make it work with the custom pistons I'm running. Might work with stock pistons but could need some modification.
$70 shipped in the USA, $120 for other locations.
