Engine Building-What Products?

The pinning is something we do and unfortunally is only available thru us. It involves making sure that the main caps can't move. Something needed on the HIGH HP items. (good safety item for someone that spares no expense on machine work).
Another item that is available only thru us is the turned down balance shaft. I did a HUGE batch so they are available at $60. We have the counter weights machine off. This gives you the lightness and the rear bearing support, best of both worlds!

I've used Motor's by Gosh before, they do pretty good work. John is a good guy. I heard he went to the Carquest in Ramsey,but might be re-starting his shop in Forest Lake now?
I have a few other sources that I wish to not disclose at this time.

The performance gains on a 3 vs 5 angle valve job are noticeable but usually not worth the additional port work required to make it worth while. As long as you have good quality valve seals, proper valve stem and valve guide install heights, and the head is flat, I would run with it. The DSM head flows VERY well for an oem product.
