Not Ranked
I have a question that may apply to others.
I have a 390 with D2TEEA heads now. A stock bottom end with the edelbrock RPM intake, 1 3/4" headers, 2 1/2" exhaust, Comp Cam 280H-10, stock push rods and non-adjustable valve train. Would these stage II heads be an upgrade I should be considering for the next level of performance.
I'm curious to know what all else I would need if this is right for me, thanks.
John
