Excoach;
I did not measure the valves out of the engine. Have your machine shop measure your stock valves and spec them to Chevy 6 cylinder valves. I purchased and installed new Mopar flat 6 valve springs. There was not much difference between the old and new. Sounds like a good price on your cam re-grind. What specs are they grinding it to? I am using two Carter B&B single barrel carburetors.
As long as you are this deep into your engine I assume you are also going to replace the rod, main, and cam bearings and turn the crank if necessary. You should also replace the timing chain and gears and the oil pump. And dont forget to replace the water distribution tube.
