says $1649 on the website correct also says add prc 66o'' springs no charge 1999.00 
The Heads are $1899.99(Intro Price) with the PRC springs. The $1679.99 price that you see are the heads optioned without the PRC spring kit(or the 918s).

Does milling the heads add a charge? I'd think with 60cc (for an 11.7:1 CR with a Cometic .040" Gasket), these heads would be a perfect compliment to the MS4 (DCR of 8.5:1).
Of course, that depends on needing to flycut. If so, one could just mill to 58-59cc and flycut.
What did the valve drop end up being? Is there more PtV than stock or about the same?

You guys are doing a great job!!!
If you had had these out when I bought my 2.5's I would have bought them. I am thinking of getting one of your 402's, so would my 2.5's work better on a 402 over these heads??
Thanks!!
