Stop in for a cup of coffee

@krazykuda, should I go to 5/16" stem 2.02" intake valves or stick with the standard 3/8" stem?

I'm contemplating going full retard on these heads. It turns out it isn't as expensive to re-do them as I thought. Going to need a ridiculous cam, too.

I would think that 3/8 with more meet will help distribute the loads better for less wear...
