317 heads vs 853 heads
317 heads vs 853 heads Whats the difference, any better with 317 heads. Or do you need to do valve work on the 317s ?
Figured itd be a good idea t post my mods, 233/239 cam,obx racing headers 3" duals exhaust, stock intake/tb slp lid. Would a 70 cc chamber be to big? what would be a good head for my setup with out spending a ton of $$

they work just fine but better for forced induction because they lower your compression ratio. really it depends on what route your taking but i would go with 243/799 heads for higher compression and better flow great budget head imo of course
