How will high comp pistons and the "S" cams run on CIS? I see the CIS as a temporary situation.
Like a dog.

If this motor is to be done in two stages then I think you'd be best off doing a stock rebuild at this point. Hopefully your pistons and cylinders are usable and don't need replacing. If you can swing it back date the exhaust system to pre-75' if it isn't already.

In stage two you can change cams, P+C"s, and induction. In stage two since you'll be changing P+C's go to 98mm to make a 3.2SS accompanied with the cams and induction and the motor will be a screamer. Scary fast.

Your ports are plenty big at this point so I would'nt touch them. They actually will be adequate for a 3.2 as well but if you want a little more high end then you can port down the road. Really though for a street motor I'd only port the exhaust to 37 or 38mm.
