ok, thats what I have, just seems like I have to drop back side of rocker alot just to get roller to center of valve on these scj heads. exaust is looking like an 8.680 pushrod which is in the motor currantly will work for exaust but intake looks to be at 9 inches and that is ck with a pushrod length checker. I have Milodon rollers
