My home inspection of Speedmaster heads

I don't think SM is going to do the work that some of these guys are doing on their heads. They are at the bottom of the barrel in pricing. I found their heads to have great casting and serviceable hardware. Really, to get these heads to a place like PBR is taking them, you'd pay a machine shop a grand at least. If you can't do it yourself, better off just buying TF.

I don't disagree with you at all. I was more addressing what PBR and others had mentioned about the valve job and even the CNC work at the port entrance and under the valve seat. Even at the lower end of the spectrum, they can tweak requirements here and there to make improvements in the final product, that won't cost them in the manufacturing process. I do it all the time with the stuff my company makes. Not everything is doable, but there obviously is some low hanging fruit here. SM won't change unless they hear from their customers. I know my business won't spend a dime on process unless there are more dimes to be saved ( and I can demonstrate that), or a customer is not happy.
