I have a 1986 quadracer and was wondering if the cool head option was right for me.did you guys notice a difference with yours??

 

It depends on what your trying to accomplish. Having the ability to change dome sizes for different applications (Alky to gas and vise versa) they are great..

Otherwise, your $$ is better spent elsewhere... It's much more cost effective to alter compression, squish, etc. by machining the stock head.

Guess they kinda look cool, but not worth the $$ for most folks.
