Trying to decide between a couple of choices, but have no experience with them. Any opinions? Comp Cams stamped, roller tip Summit brand roller tip (I question the quality) Comp Cams aluminum, bearing fulcrum, roller tip Summit knock off of the above (same quality concerns) I guess I would like to know if the low prices on the Summit rockers are worth taking the risk. I'm looking for some 1.5 ratio rockers to use on 882 heads. The valve spring rate is only slightly higher than a stock spring and I'm using a Comp cam extreme energy cam.
