Of course, I'm not telling you anything you don't know, but there's no way E heads will ever be as cheap as Speedmasters as long as they're made where they are, and Chebby Es will always be cheaper than Pontiacs simply because of demand and market size.

Given that the R&D costs have been wrung out of these heads a long time ago and that they are run in batches when demand calls for it, there's no reason other than additional material (anyone know the weight difference between an SBC and Pontiac Edelbrock head?) or additional machining costs for the heads to be any different in cost than an SBC that they make other than they CAN charge it if people keep buying them.

Pontiac heads go for about $200 more than the equivalent SBC head, based on a quick look at Summit's website. If you keep paying it, they'll keep charging it. Unfortunately, our community is significantly smaller than the Chevy folks with limited options.

Regarding the information on the pkelley website concerning the valve timing overlap ranges that are most likely to work correctly linked in post 82.

One might question if those numbers suggested by David Vizard are significant for his work typically on a small block Chevy application.
