hey just wondering what you guys think this super big valve head job will produce... lets turn it into one of those guess comps. whoever gets the closest to the rear wheels output, i will give my old 1600 donk to (if you want a big arse paperweight!!!)

Did you air flow trest the head? I would like to know what improvements it made to air flow. The large inlet valve must come close to the cylinder, perhaps even shroud flow a bit. What exhaust valve size was used? The shape of the chamber looks good ... they did a good job of welding and grinding so that each chamber looks the same. How much did the head mods cost? How much lift has the cam got? Crow's 0.4255 inch lift just clears a stock piston with 0.060 clearance, using a piston with 0.015 deck below the block.

I figure you will make about 92 KW at the wheels, about the same as a V6 Commodore and that is about 140 Kw at the flywheel.
