if you have a 383 stroker engine with factory heads and you change to a good set of heads how much of a hp change will you be looking at? ballpark of course and what heads work best on these cars ?

 

Little shop in Concord NC does a mean set of ported stock heads arguably one of the best options out there even compared to most of the aftermarket stuff.

Depending what cam you have now it is not out of the question to gain 100hp from good heads and cam.

 

what the name of it?

 

Get the stock heads ported by Elliot Portworks or Advanced Induction.

 

where are they located? how much ?

 

Heads are where you make the real HP on any engine!
