Welding up the exhaust port floor is stage 1 to porting the head, after welding, the head will be warped and need straightening, so if you are ever going to use that head for a decent increase in performance, it is step one.

If you are doing as little as possible to your motor, why shave the head to B18B thickness? Healthy stock B18B are a pain because they tend to run on and demand 100 octane. Just leave it thick and use regular gas. Cam and compression are tied together too, if you have 10:1 compression, you must use atleast a C cam.
