Speedmaster Small block porting tips and results Part 1

Yes, but the bare Ede head isn’t ready to be assembled and run....... they have blank seats and no valve job.

The SM bare head is finish machined the same as the assembled heads.

Sure, that’s nice benefit with their bare head vs the Ede head.
But you’re comparing a finished head to an unfinished head.

I guess my main point being...... if one buys assembled Ede heads, that’s not how the seats are.

If you buy an assembled SM head, the seats are the same as the bare heads you bought.
