Troy,

There are probably a lot of people who have put in time on those heads but I doubt that many have devoted as much of their life to them as Mike Kirby, a partner of Kay Sissell back in the day <http://www.sissellautomotive.com>. Mike has the molds that he and Kay designed and casts up a pallet or two of castings every year. Watching him machine a raw aluminum casting into a race head is a fascinating way to spend some time.

A couple of years ago, one of Mike's customers wanted a fuel injected 250 so he fabbed a manifold, we hooked up a Holley Commander 950 FI system and he and I spent a couple of days on his dyno sorting out fuel and timing maps. That was a very responsive little motor.

In addition to the aluminum heads Mike has a comprehensive product line of bolt-on components for those motors. He runs Kay's old twin-six dragster on the nostalgia circuit with some success. Last time I talked to him he was experimenting with running nitro in the dragster.

It would be worth your time to call him (number is on his website) and talk about what he has to offer. Mike is a great conversationalist as well as a died-in-the-wool six-banger gearhead.

Good luck,

c
