whats it cost to prep a set of used eddy rpm heads to these numbers? or even not that radical just some moderate port work to increase the out of the box numbers.
To prep used RPM heads for the low end is $600. For the ported and upper end used RPM's it's $1,200-$1,800. We do not CNC heads, all of our porting is done by hand.
If the TrickFlow heads can deliver what they claim, they are going to be a great deal and Edelbrock will have to step up their game.
To this point in time, no cylinder head has ever tested to their claimed OOTB flows on our flowbench.
