Gray Head

Do you want to sell the 582 mod 90 Gray head and buy a 582 mod 99 Blue Head? Or do you want to physically swap the cylinder heads from grey to blue?

no thanks i love my Gray head, runs so smooths. its like me old and gray headed. ?

Any issues with just swapping the blue cylinder head onto a grey?

I have a kitfox with a blue head engine and a new..old stock grey head..reason for wanting to keep blue cylinder head is so I won't have to modify cooling plumbing.

Swapping a Gray head to a Blue head engine can be done but you have to do some modifications to the cooling circuit.
