I can do port matching on the manifolds and heads if you think it's worth the time. Right now the intakes manifold openings are slightly larger than the manifold outlets (theoretically reducing the backflow). Gaskets are cut to be out of the way. I've already modified the Kadron manifolds to open them up to about an inch from the bottom. Seemed to be idling fine before I dropped the engine.
I'll measure the rocker lift ratio directly tomorrow to see if I screwed up the arm length measurements. I'll raise one side an inch and see how far the other side moves.
Rookie question, when heads are designated as "042" or "044" what does that mean? I can see that it doesn't directly correlate to valve size. I'm sure it's obvious but I've not been able to figure it out.
