The only part I am not clear on (as I have just started the research) is the pocket porting. Does anyone have pictures, details, etc?

How much air flow is gained by using short bolts (countersunk) in the 3 locations where the intake ports are, cleaning up the area and closing off the top with a 1/2" npt plug?

I know the 194 head has smaller chambers. That will wait for now as these are getting really hard to find.

Summit has pistons, etc for a rebuild when I get that far.

I had planned on making a custom intake and running a pair of 2-bbl, or 3 1-bbl carbs if I stay old-school on the engine. The other choice was a modified TBI setup from an older 4.3, using the distributor from an '82 california emissions 292 (computer controlled) and a pair of 2 liter throttle bodies. That would give me a simple EFI setup with old school twin carb look.
