This shop mainly does allot of work for the local guys running at the 1/4 mile speedway. Because of the racing rules that state you are not allowed to add foreign material, or grind inside the ports, we're pretty limited as to what can be done. The rules also state that any cut over 60 degrees must be concentric to the valve guide and may only extend 1 inch below the valve seat. Since most valve jobs only reface the 45 degree seat, and "perfomance valve jobs are 3 angles (30, 45 & 60 degrees), there are some opportunities here. If you add a 15 degree cut to blend between the combustion chamber and the 30 degree cut, and a 75 or 80 degree to 1 inch below the seat, you now have a 5 angle valve job. Add a 30 degree back cut on the valve face also. The end results were no less than astonishing. At the upper end of the valve lift spectrum, the ports flowed over 10% more, at the lower end of the valve opening (.050) the head flowed over 200% over thee 3 angle valve job head! Using the formula for horsepower: HP= CFM * .2527 * # of cyl. The SBC engine was dyno tested before the teardown at 525 hp. The port actually flowed at 260 CFM max. Which directly corresponds to the above equation. With the 5 angle valve job, and the back-cut valves, the same port flowed a maximum of 292 CFM! Which by the above equation = 590 HP! I can't wait to finish these heads, re-assemble the engine and get it back on the dyno. There are still a few more tricks up my sleeve here that will surely put this engine well over 600 HP. So if you're looking to get some additional torque and horsepower out of your engine, consider having a 5 angle valve job and back-cutting the valves. Good Luck and as always, your results may vary..... Scott Cable Jamestown, ND s2cable1@yahoo.com --------------------------------- Yahoo! Sports Rekindle the Rivalries.

I used "wood washers" (large steel washers) on the back side. My gear is 6 inches longer than standard Diehl legs and my KR is 765 empty, which would add more stess to the fitting, and I've been on grass strips a number of times.

I made my own formers and used 1/16th Hoop Pine plywood for my turtledeck. So far, it is okay. If you are interested, I can tell you where to get it, in Houston. The weight may be less than a pre-mold. Good luck.

It is the 8 bolts per side(4 an-3 and 4 an-6) and it is the metal to metal of the wing attach fittings. I just wanted to make sure I don't have a silly mistake for FAA inspection next week. I'm certain that the nut should have a washer at least to keep from gauging the attach strap. But I'm not sure if it should have a washer under the bolt head to spread the bolt head pressure out on the wing attach strap. Joe Horton, Coopersburg, Pa. joe.kr2s.builder@juno.com BTW- I just received the fast turn a round in history from the FAA. Sent my paper work for review on Saturday and got it back in the mail today all reviewed and with only 3 small comments to change. I hope the plane goes that well.
