Trying to decide on a head for a usra modifed . I'm stuck between going with the brodix spch and AFR 220 eliminators. They will be going on a 383 with 14 to 1 pistons with 64 cc that is anyway. Cam is roller is .630int .630 exh 305 310 adv. Dur. What does everyone think the pros and cons are of these heads
