comp xe cams are some of the noisey ones
BTW guys
when you take a cam designed for the base circle of a SBC and put it on the larger basecircle of a MOPAR or BBC the nose gets not so pointy
which is a good thing with the heavier valves of the MOPARS and BBC compared with a SBC
If you are buying new valves SBC valves are a cost effective altrnative and a performance benefit
