Metric Motors has quite a good reputation for a quality product.

I also need to find someone to do the 617 head.

The only issue with them is the shipping from the Northeast out to California and back. This is likely to add $300. to the price

I don't think I want to trust a head to UPS or any of the package delivery services. This leaves the LTL carriers which are quite costly.

BTW, you don't get any new valves for that price.
