Thickston Heads

Does anyone know how to tell reproducrtion Thickstun Heads from the original ones.

 

Do you mean the head covers or they actually heads?

 

Actual heads

 

These are actual heads- 24 bolt-huge old style spark plug holes. Have Thichstun and Los Angles cast in the aluminum- no fins.

 

bill,
to my knowledge that have not reproduced these heads but i could be wrong. you will get a better response if you post on the hokey *** message board.
