1937 Knucklehead Bare Heads For Sale $4,000 or interesting trades?

I have one pair of 37 Knucklehead heads left. They are bare, high rib heads with the drilled, tapped and plugged primers. Only a few broken fins and no cracks on the front head. No broken or repaired rocker box platforms. Price is $4,000 delivered to Rhineneck in early July. Partial trade considered on rare Knuckle and or rare Indian parts? Located in New England. 46EL
