You will be better off with heads with slightly smaller intake valves. 2.10 valves are going to be too big for a 346, in my opinion. Of course everybody has an opinion and I'm sure some will be different.

^^^^^Agree, that large of a valve on a 3.898" bore is going to severely impact cylinder head flow. IMO, I wouldn't run these on a small bore engine.

That is definately a big valve! I bet your valve drop is probably really bad with that large of a valve.
