Isn't that a bit of lovely work Joolz.
Have you fitted it yet? Result? Compression must be high..?
Looks great. NZ yer?

Thats not my head, mine is a big fin head thats ported and flowed, but has a standard combustion chamber. I put that picture up just to show the difference on the CW heads

Would you be able to post another pic of your head?
It's taken a while but I've finally tracked a fellow down that can do the work I'm wanting. Won't be modifying the chamber either. After a lengthy conversation with him, I don't think the mod will produce that much of a difference in HP for the cost.
A bit more cash to play with a decent stainless exhaust I think is best.
