According to my info straight from BBM, the bare head pricing will be $1350 per pair. At this time, there are no plans to offer a "complete" BBM head FROM BBM. The plan is to sell the heads bare, and any and all finish work pricing would be decided between the buyer of the heads, and whoever does that finish work. Some BBM dealers will be folks who can offer the service of taking the bare heads from that point to various stages of finished heads.
I am doing some testing for BBM now. I have a pair of the heads here. I will have info and opinions very soon. I plan to do some very thorough testing, and will be able to offer my opinion and conservative flow results very soon. As some may know, if a head flows good here on my bench, it will flow better other places. I do not know the numbers yet, but I will put my seat work on the heads, with no work further down than 1/2-inch below the seat, and share the results fair and honest, for all to see, on this forum.
From what I see so far, I like what I am looking at. As cast and sold, the exhaust throat can accept 1.57 diameter valves if desired for small bore apps, or with an exhaust bowl cut and valvejob they can accept the larger valves. The intake bowl, as cast, will do well with 2.15 or larger valves. A person would not want to use an intake valve smaller than 2.15........BUT........the valve placement will compliment the use of a 2.15 diameter, even on very small bores.
As soon as I have some accurate info I will post it. Bare BBM heads are available now.
