Mercury promax / 250 xb heads

[Lake rat Skater]

I have a pair of c10 heads off a 300 promax that blew. 1 head is good, the other is questionable from the cylinder that blew. Make me a fair offer

I had a pair of good condition c11 heads off a 2001 250 pro xb. Also make me a fair offer.

Thank You

Bump, the promax heads are sold, I would still like to sell the XB C11 heads.

Thanks,
