After a strong desire to see more Buicks in the 7 sec bracket and John Everett's (SUPER CAT) dragster in the 6's and eventually in the 5's, we needed 21st century parts. Heads that flow over 500cfm. Now we have them! The road was very bumpy and slow, but now it has straightened out. The CAD files are complete on some items, Blocks and Heads, with others underway. We will be doing the machining in-house for most products. We have bought the "state of the art" tooling for blocks and heads, rough and finish work, we own them! You wanted them and me too.... SO HERE THEY ARE!

Yes, but what we call "drag race water"... they gun drilled passages around the combustion chambers, and front to rear in the billet.. Since we have not used these yet, we are interested in just how well they cool, but it's generally accepted in this form of cylinder head, that it won't be like a cast head with a water jacket, and street use is extremely limited, if at all. We will know more here in the next few weeks, since I decided to stop wasting time sleeping, and am now balancing a full work load in the shop, with this new project.. the first Billet head 555 will go on the dyno in a week or so, for extensive dyno testing. I have one Tomahawk on the stand now that has to see the pump first, but after that, we are full speed ahead on a big development dyno test.. And then, if things go as planned, we should debut those heads on the race track here, at the GS nats later this month. It's an ambitious plan, considering what else I have going on, but hey, if you put every waking minute into this stuff, work nights, weekends and holidays, and sleep just enough to keep yourself sharp, many things can be accomplished in a short time. Here is the picture that is missing showing the water passages drilled down around the combustion chambers.. they are behind the black plugs.. JW
Not really tall overall height as the valve cover is short in height. The rocker area of the heads were raised to help prevent oil from running down the block when servicing the valve train. In our application it helps with pulling heads between rounds for engine rebuild. The heads also have finger lip to help hold onto them in this process
I thought it should be bigger but the smaller we go the more the flow picks up. That tells you the importance of getting the valve away from the cylinder wall. Another reason canted valve heads work so well. Also on the list. When your ready for Pro Stock let us know!
I assume a true race oriented intake for the tall port stuff is on the drawing board? Or will you just be doing intakes for your heads?
Ken, With all these new goodies, youre making me want to spend enough money to potentially end up in divorce court...... Seriously though, you're coming in like a lion with this stuff. Hats off man, I'm really impressed. I hope to spend a lot of money with you in the future.
I like the lift numbers most of us never see over .650 lift on a buick, the flow chart goes almost twice that. I can just see the massive valve notches, or see the spring pressure numbers over the nose on a cam going almost 1.250"
