stealth heads on a 383?
The last time I bought the valves like in those heads they were $20-$22 each. But as we know the price more than likely changed since then, and that was just last fall. Guides are $148.00 and seats are $200.00 as I use Serdi seats. Milling is $55 for the first .030 per head then it depends on how much more you would want off. As the intake side would also have to be milled for the intake to fit. At a rate of $1.00 per .001, .040 = $40.00 an so on per head. The VJ is $250.00 and the porting of the bowls and gasket matching is $400.00.
So you would be looking at about $1,108.00 plus parts and shipping.
As for the stealth heads I haven't as of yet.
