Hey gents. Was wondering if anyone knows where I could get my hands on a set if the 1:9:8(?) Ultra High Ratio Rockers similar to the ones that Mace sell for the Ecotecs, but for my S1 Buick? I had my heart (and wallet) set on throwing a cam in there for some more poke, but it was brought to my attention that no amount of exhaust modifications will be able to mask the raspy lumpy sound of a cammed 6 at idle (Trying to be discreet here!). Any information would be greatly appreciated! Cheers!
