AMC is an aftermarket head caster, and I think they make the clearwater head. It's a good head.

You really need to lower the compression with Starion pistons or similar (8.25:1 or lower - stock is 7.0:1 for Starquest pistons, 8.7:1 for carb 2.6), and I really like the piston squirters, which can be retrofitted into most 2.6 blocks. The rest of the motor is mostly ok. Have to use the Monty oil pump and pan, though. The actual work is simple, and I think you can do it. It's all worked out now....
