in mine 93 Cobra svo conversion 160 rwkw... TFS stuff 180 rwkw on different dyno though...Same cam & throttle body on both.. May have got more with different cam [more lift] and bigger throttle body with latter....If not going forced induction or stroker 58cc chambers helps heaps esp off cam....
TFS[or any good aftermarket heads] work well if stroking or turbo ..forced induction...

well dollars pending i wanna go 347 stroker heads and intake whatever works best vs price and the a 200hp nos kit

"Torque" to your engine builder about compression with a stroker generally compression is lower with these heads as they'r made to fit 351's as well..There are different size combustion chambers too..

imo don't get too carried away with strong/ heavier crank as the weak part of a 302 is the block,get good pistons and rods though. Ever heard of a 302 breaking it's crank? No !!
