For street use, 1.9's work very vell, anything over 2.02 there are many flow problems that occur at low rpm's that can be overcome easier with a little smaller valve and fine tuning.

The 1.930I. and 1.600E. Chevy dimension valves are probably the easiest to obtain.. Stem diameter (11/32") is the same and length is very close....Does require enlarging the seat and opening the bowl area, and non-rail rocker arms.

No worries, just a little material removal by the shop which does your valve job. That's stock W sizes IIRC...

I've run as large as 1.9 IN and 1.6 EX in early heads with good success.....Cut down 1.94 and 1.625 Chevy valves on the valve grinder. Definitely needed bowl work with those though..
