Haven't posted here in a while - hello to all.

CNC,
You just posted a pic of the 12 port head on a thread in another forum.

Put me on 'the list' when you get these heads ready for production or ready to take orders.

What size are the guides, spring pockets, valves, runner volume? I did see you posted that they'll run BBC rockers. Do you have a link to the head specs?

Would you consider this head streetable?

Are cam recommendations the same as for the stock/lumped head?

You mentioned in the other forum that this head has potential for an additional 150 hp. If it is used in a lower compression setup (less than 11 to 1) what is the 'bolt on' hp increase estimates? (I realize there are alot of other components that affect this, but...just wondering of a ballpark estimate.)


If anyone thinks I should start a new thread for these questions, then let me know and I'll do it.

Back acouple of years ago you mentioned your involvement with Cotton Perry. I've directed alot of people (moslty SBC guys) to read about it and most everyone is dumbfounded with what he and his team were accomplishing 30+ years ago with a 292!

If at first you don't succeed,
then read the directions and try again.
