I actually spoke to you last week ( not on friday it was earlier in the week )and you ( unless there are two matts there ) told me that you had no info on these heads yet and that there would be posts on the boards when there was some avail... Im Not jumping on you guys but I had credit card in hand ready to order.

If you called before we had information, yes, you would have been told that. We had all the information, including firm pricing, as of Thursday afternoon.

Any flow data on these heads?
Also is there any info on any of the cars with the 427`s that got the first run of these heads?
Ive bought everything except my current cam from you guys and I know If I was given access to the first run of these heads there would be dyno and track numbers already posted. Just sayin
