personally i wouldnt go over 6*s on the split, reason being you'll run into ptv clearances, stay around 607/612 on the lift i personally would stay around 235/239 which is pretty maxed out on the a lq9 with l92 heads thats a tight duration which you would need to widen the LSA to around 113.1 or so..


get with patrick G, he spec'ed both my cams with great success
