JMO, 12K for the top ends mentioned from Gaby doesn't sound too crazy to me. I paid 8K for my CV top end, but I didn't have Ti valves, my rocker shaft cost $1275 instead of $1600, I bought my 2 carbs used for $1500 ( originally built for Don Greene/Top452), and I didn't pay for extentive manifold work for a single fo intake.
Had I been able to afford Ti valves...add another 2K. Robin told me on the phone the year before he has 35-40hrs of porting to his single fo. If I had chosen to pay for 35hrs of intake port work, how much extra would that have added?
I could see it costing me 12K for my top end had I been able to afford some of the fancier items.
For a top end of a combo that runs 8.4's at 3300# seems to be reasonable and in line with any other head combo at that level.
