Is it worth it?

I haven't pulled the head, nor has he. I don't personally know the guy but saw he was looking to get rid of it.

so
engine - 150
Piston/rod - 78
springs (would need replaced anyways)
heads - 450
sleeve (worst case scenario) - 80

vs 1500 for a runner.

Sounds fair enough to me. What do you think? I'd love to be able to pull it apart first but I doubt the guy would let me do that.
This would be a good candidate for my dart, no?
