On a side note. It looks like those heads a built pretty beffy. For example, I look at the intake ports and they are begging for porting. Also the intake cams look like thay have a fairly short duration compared to the exhaust side.
Overall the head looks good, no scoring or discoloration on the lobes; only minimal carbon buildup on the valves. The only thing I can think of is replacing, or at least cleaning, the rusty studs on the exhaust side.
Price???
