I would take $300 for the head. It has about 15,000 miles since a complete valve job with new guides.

There are two different type prechambers, and I had to change them to match the pistons I used. If I remember correctly, the prechambers are the ones that are cylindrical with an angled cut. The other type have a rounded end. You need to check to see which ones you need to match your pistons.

Have a great day,
