Here is an example of why machine shops are important. Here we have a brand new, right out of the box, set of heads. After inspecting the valve job, we noticed an exhaust seat not sealing. I lapped the valve in, had a nice thin line at the seal. However, after looking at the seat, we saw that a fair amount did not lap in. We can fix that. As we can see after the matching high performance exhaust seat valve job, we now have a complete seal. Something to consider when building.

INVENTORY BLOW-OUT!!!! ALL VALVES ARE GOOD TO REUSE!!!
We are getting ready to clean out some of our shelves. See if we have anything you need or might need in the future. This will be for Intake & Exhaust Valves. All valves go through our clean, polish, and reface stages. If we see anything we dont like, we wont sell them. Our goal is to try and keep the cost of good used parts affordable. Below is a list of Int/Exh valves that we currently have available. The description will read as follows.
Stem size X Head Dia X Overall length (3/8 x 1.890 x 5.450). Feel free to reach out if you have questions or would like some pictures.

We have had requests from several customers about dates the 65 North Pickers will be playing in our area this Spring. This tour schedule was just published, so we are proudly sharing it.

May 20, they will be playing at Martyr’s in Chicago.

Google them, give a listen on YouTube and Spotify or find them on Facebook. If you like fast boats, fast cars and fast paced music, you’ll enjoy an evening with the 65 North Pickers…. (and Grandma said it)
