Super Duty Race Series Stainless valves: 11/32 2.150"/1.680" - designed specifically for the BBM cylinder heads.
There have been numerous inquiries as to what valves to use with the BBM cylinder heads. During the development of the BBM heads, we flowed quite a few valves from different manufacturers, with variations on valve head shape and size. We eventually settled on the 2.150"/1.680" combo that we are now using.
Later testing showed the 2.150 intake valve to flow as much as a 2.190 intake, (both w/only minor blending), but with better port velocity. The intake bowl was optimized around the 2.150 valve. Testing different exhaust valve head shapes, we selected one that really emphasized mid lift flow, without sacrificing upper lift flow. This special exhaust valve is available in both 1.680" and 1.710".
As neither of these valves were readily available from any manufacturer at a moderate price, we've had to have them built specifically for the BBM heads. It was decided to only offer a premium quality, Race Series valve, instead of the budget priced "E-Bay" level stainless valves, or even the mid range type re-builder valves. We just didn't want to have to deal with all of the quality and durability issues of the cheaper level valves.
Blue Oval Performance Engineering is the only source for these valves. Bulk purchasing has allowed us to keep these premium valves reasonable. A set of 16 valves runs $309/set. (Compare that to the Ferrea F1186P 2.150" valve that runs $200/set of EIGHT). We have 2.250"/1.710" valves for big valve head/big bore applications as well.
In answer to customer questions: Yes, you can get the 2.150/1.710 valve combo for the same price & Yes, these valves can be fit the Edelbrock FE heads.
Valves can be purchased alone in sets, or as a package: Bare BBM heads with Valves for $1630 or as custom built head assemblies with our special valve job starting at $2300 and up, depending on spring & retainer choice, or milling for smaller chamber volumes, etc. (Heads are running 75-76cc's).
