Speedmaster Small block porting tips and results Part 1
Looks like they cnc’d some of the 45 away on those seats.
Imo, that cnc’d chamber version really needs a bigger intake valve, a valve job, and some blending around the seats.
Nothing about the way the seats are done on that head does anything good for the flow.
My advice....... buy ‘em bare and have them “done”.
If that puts you too close to TF money...... then buy the TF’s.
