ProComp/Speedmaster aluminum heads
That's IF you fit that bill.
Anyone can hand you a set of AM heads to toss on and 'better chance than not' you'll go faster... but whats the difference between the heads, beats the **** outta you, right? Not just formulas ...I'd rather learn 'with my combo' what amount 'more' airflow did i need to raise the mph to.. ? and lower et to..? etc and did i just waste a set of heads and hurt myself or did do decent and can build upon that knowledge.
