Stock L98 113 port sizes?
Does anyone know what the stock height and width of the 113 casting aluminum vette heads is? I looked and searched and didnt come up with anything except here 1.220"x1.929", 2.353 sq in. Which sounds large and these may be in fact, ported. Thanks.

I do not know, but I have a couple of friends about to work on a set of NOS ZZ4 heads. I will ask them to get measurements and the dimensions at the pushrod pinch.
