    Need help.


    First post here so take it easy on me. I have a 1980 C3 Corvette with a 79’ 350 4 bolt main that has domed pistons (dont know the exact dome measurements) and has been bored with a compression of 9.5:1 with 487 heads on it and an L82 cam. Im going with an edelbrock Performer RPM air gap intake with a holley 670 double pumper. Im looking for a good head spec (intake, combustion, exhaust size) to wake this motor up and possibly boost the compression a little while still being able to use pump gas (93). Ive heard the dart platinum pro 1 (IRV 180cc) (2.02 intake) (1.60 exhaust) With a straight plug (i have header side pipes) may be a good choice. Im aware some heads have 1/2” higher exhaust ports and with the way my side pipes are mounted i want to steer clear of that. . I want to make sure i get exactly what i need that will work with my motor to add some power that wont be overly expensive. Any advice for any parts i should use on the head will be appreciated. Thanks so much!2348E0F5-C774-43F2-94E3-87CD81EC40CD.jpg
