Joe,

only suggesting that kevin run the low riser , his line says original 428....stock 352, 390, 428 heads are all ( with some spectacular rare exeption) low riser heads .

I dont know much about aftermarket aluminum heads, whether they are a compromise to be port matched or whether they are low or mid riser or even if they are both available??

there are guys here who know Edelbrock absolutely .........cmon boys , pipe up.
