My home inspection of Speedmaster heads

I still think the unported bare heads like PBR bought are a great deal.
You couldn’t do much of anything with stock castings for under $450.
With a nice valve job and a quickie blend...... they’ll be better than 90% of the bowl blended iron stuff that’s currently out running the streets.

Even though I think they’re a good deal....... I don’t think they’re all that special ootb.

But, I am looking forward to 318wills results.
Whatever the outcome....... as long as he doesn’t swap a whole bunch of other stuff along with the heads....... it should be a pretty good real world back to back test.
My cam won't favor these heads... but still looking forward to the results. My cam is 204@050 .427 (intake); little more duration on exhaust (212??@050) .455 lift. I think the results would favor the SM heads more if I had around 230@050/.480 lift
