I have a set of w2 heads. On top of a 11.5-1 408, with a .590 MP cam it ran 10.40s with ease.
In a car that could be used to complete Drag Week?
In other words.......... Streetable gearing and converter?
Closed exhaust?
Before you pursue this any further, serious consideration should be given to adjusting the budget, or your expectations.
A quick search revealed 2 sources selling 48* W2 heads P5007445AB for about $400/ea bare.
Ultimately, I think this is going to be the least expensive way to get into a 48* top end.
Off the top of my head, I'd say that with the basic machining needed, and "middle of the road" hardware, some minor porting....... You'd still easily spend somewhere in the $2500 range to have a set of ready to install heads.
Then you still need rockers, intake, valve covers, W2 headers.
