[1]Interesting things happen when you combine ingenuity, good old hot-rodding, and a CNC mill just sitting there begging to turn blocks of billet into chips and artwork. A great case in point are the Granatelli Motorsports [2] “super tall” LS valvecovers we’re using on Project BlownZ [3]. Designed specifically to clear tall valve gear like Jesel’s shaft-mount rocker arms without the use of a spacer, these billet aluminum covers are available with rocker oilers (Part number VC-0081 [4]), or without (Part number VC-0081X) like ours.

Concealed beneath our Granatelli covers are Jesel shaft mount rockers that require plenty of extra clearance.
[7]Granatelli’s optional oiler-equipped valve covers are set up to provide additional valvetrain cooling and lubrication from an external oil supply.
For those needing extra valvetrain cooling and lubrication, the versions with integral oilers have removable jets, and both versions are set up with enough material front and rear to add -8 AN breather fittings for dry sump scavenging setups. These super tall covers join Granatelli’s tall LS covers, also available with (PN VC-0019 [8]) and without (PN VC-0018 [8]) integral oilers, and a tall cover sans-oilers, but offering integral coil mounts instead of the smooth-top setup (PN VC-0017 [9]). Finally, for those looking for a standard height cover with coil mounts, there’s Granatelli’s part number VC-0016 [10].
No matter which you choose, you’ll get a super-clean billet look, top quality mounting hardware, and a factory-style O-ring seal. We’re very pleased with the design and quality of our covers, which offer a step up in strength and style from the fabricated covers typically used with valvegear that requires extra clearance. Plus, the one-piece billet construction means no warping or flex as the covers go off and on for between-rounds maintenance, providing a consistent leak-free seal.
