Am building a 383 and am looking at the fast burn heads and need to know what piston do I need to use to keep streetable . I do not want to run race fuel and I am using a roller cam . The car is an automatic weighing 3100 lbs .

 

i got silvolite KB signatures in my 383 and it runs at 9.5:1 compression with my world products sportsman II 64cc heads. thats pump gas friendly.
