fried guy doesnt seem to like porting..?..i like to do a good port gasket match blend it 2-3 inches into the manifold(and heads).i dont feel a difference,but every little bit helps,and thats performance.
performer is a awesome street manifold. i have been surprised by the engines beneath them. SURPRISED!!!
