The problem with the shims, is that with very high lift cams, and high RPM, the shims tend to get thrown out of the lifter, and usually destroy the head. The better way to go about it, is to use Alfa lifters with the tiny shims on top of the valve stem. Eurospec sells the Alfa lifters, or a copy of them, for an assload of money, over 30 bucks each IIRC. Last I checked, the same part was about 5 bucks from an Alfa supplier, or 30 cents from a junkyard.derracuda said:i got an idea. titanium solid lifters. made to accept the factory shim pucks.....eh, sounds good, yes, no :?
do the hydraulic lfters come apart? i'm guessing that the lifter itself is a cartridge unit that sits in a steel body. maybe the body could be made of titanium and the lifter cartridge installed in that.
