Well, let's see.

You can buy KCR's Stage 2 heads for $2295. They flow....what...about 320 on the intake side? That's completely assembled and ready to bolt on.

A set of bare (without valves or anything) BT's are $1300. Could you unshroud the combustion chamber, mill them down to achieve a decent CR, buy SS valves, locators, seals, springs, retainers, and locks for the difference? And would they flow 320 cfm?

You're looking at say $200 for a set of SS valves, $50 for locators, $25 for seals, $150 for springs, another $150 for retainers, and $25 for locks.

That's about $600.

So we're sitting at $1900 so far....for a head that still doesn't have any machine work done to it...or anything done to it to promote air flow. A guy on the FE forum has a set of untouched BT heads....and they only flowed 267/197 out of the box. That's not much better than the Edelbrock head. So add money to port the heads to put them up to the Stage 2 Edelbrock range.

THEN....you have to buy special stands/rocker arm setups.

Keith uses an awful lot of Edelbrock heads. I think I've heard him mention that he has a CNC program for BT heads...but it requires a lot of machining to get to the point where he can CNC them....

Maybe he'll chime in here.
