Edelbrock / RHS heads, or go BIG block and put it to bed!

Those eddys should be flowing in the 275 cfm range OOTB for the cost.
They should a;ready flow what a full ported j does OOTB
Otherwise...whats the point....it's just a boarder line race piece that needs TLC [or as much as the org purchase price to get them worked] to make the hor$e power.
Im just bent that the buttlers have 30 heads to choose from that flow 280-300 ootb
and we have about 4 choices that only go 245cfm that will accept stock int/exh patterns.
