Damien,
Like any motors a lot of horsepower can be added but it will take a fairly big pile of cash to get noticeable difference.
The quickest red six that I built had some serious porting done on the inlet/exhaust ports both at the inlet/exhaust po

For a P-plater this is what I'd do. It will give you a good driveable car with excellent torque:
Red 202 block with rope rear main seal;
Blue crank and rods (new rod bolts);
Red head with inlet posts removed and slightly larger inlet valves |

Byron, At what point would he/Any one start the Duel system from? I understand this would help in Torque, And likely shifting The Power band.

The reason for dismissing the blue head was if you run anything other than triple twin chokes there is little point, at least on a 'street' engine.
The dual system should start at the X2/GTR/186S/XU-1 exhaust manifolds. These are two piece, three cylin |

Yep So a set of old six cyl Tri-Ys will do the trick then, While cutting off the last collector and running the Tubing from the two Secondderies left. (2 of, 3 primaries leading into the first two separate Collectors)
The Blue Head add in was just a ge |

I wouldn't touch extractors - leave them as they are, although you would probably gain the same benefit by following the same process, so you are effectively 'tuning' the pipe lengths to the engine. I was talking about cast iron GTR exhaust headers. Holde |
