Fish,

I'm comparing a stock 1.8x 318 valve to a 2.02 340 valve diameter. Cmon Man!

Do you work for MSNBC?

Where is the compare? This is what you wrote!
And my reply

Better flowing head than a 318 stock piece with 2.02/1.65 valves.

Let’s do some math here. 3.94 bore size, 2.05 + 1.60 = 3.65 which leaves .029 to have clearance for the valves to operate.
Ummmmmmm, not a great idea.
Besides, in all honesty, I HIGHLY doubt you’ll need a 2.05 valve in a .030-318.
