thats a big lost off changing heads and a air gap.

 

so assuming that everything that is listed is right
what heads do you suggest i go with to get the max potential out of this motor....ty

 

there are tons of different types of heads out there. its all depends on what u want with them. u have square, oval port. then the springs.....etc

 

Check to see what heads are on it now...when you get back..from there you'll be able to see what to step up to. it may have a decent set on it. thats just alot to lose from heads...and the spacer is only good for about 5 hp in some cases.

 

that is what i was thinking.

 

well they are fuely heads now?
dont know anything about them

 

they are what?

 

fuely heads (ported and polished).
