Am curious how many people on here run these heads on primarily street oriented engines that see some strip action. I'm dead set on keeping my cam (.499"/.510" 221*/225* @ .50", 112* LSA) and using a performer intake I just picked up along with a 65 mm TB and 70mm MAF; still not sure if I'll have to jump up to 24 lb. injectors or not. Would these heads be a good fit for my combo in putting me around 300 rwhp while maintaing decent bottom end power (as much as the cam will allow)?
