Ez...I had them made by Dave McGrath at C.E.P.
Custom Engineered Performance CEP - porsche 944 dry sump
Yes they will be far better than stock...but mostly on a racetrack. These are quite a bit larger in diameter than the stock ones. They will help the engine breathe but also at higher rpms. I also have one of his CAM wheels, fuel rails, dry sump kits, a/c delete brackets, turbo mounts, AOR delete kits and more to come. Damn fingers crossed to have this motor on the dyno next week...but I get sick of typing this...ergh....
