I'm  not trying to "one-up" here, but a modern car with ALUMINUM HEADS and 
ENGINE MANAGEMENT has a few advantages over a cast iron engine with 
(likely) sub-optimal ignition timing (and the possible sharp edges).

These are two completly different animals.

Regarding TR6 heads, you can actually cut quite a bit and not introduce 
sharp edges and you can "fix" the probs with a dremel tool and some 
quality time.
