Edelbrock heads will work but they are no where near a Trick Flow head. A Twisted Wedge head outflows a Performer and Performer RPM head across the board by 20+ cfm. If you can find a set of Performer heads cheap, get them. Otherwise be patient and look for some Twisted Wedge or AFR 165 heads.Came across these just wondering. I'm going with fcam and track heat intakes for sure. Will these heads work in the combo at all?
Anyone know if the springs could handle the lift from the fcam?
