BBC Valve Cover Clearance

I'm building a BBC for my 1967 Camaro w/ power brake booster (standard size)...I have the correct BB engine mounts, heater box, etc... Does any one know if all low profile valve covers will clear or does it have to have an indented section at the rear like the originals do?

I'd like to use a set of Billet Specialties Low Profile Aluminum valve covers. See attached pic...

Any comments or pictures are appreciated...

Re: BBC Valve Cover Clearance

Standard height finned Edelbrock or M/T's will fit. If you run a Stud Girdle and have to use a Tall Cover you will have clearance issues with the Brake Booster and Wiper Motor. About the only way to retain the OEM Booster and Wiper Motor and run Extreme Lift cams with Hi-Spring pressures is to use Shaft Rockers under a Standard height Valve Cover.

Here is a PIC of a members BBC in a 69 with M/T's - No clearance issues.

Re: BBC Valve Cover Clearance

my 67 with a 454 has plenty of clearance with a factory type valve cover and the standard power brake booster, however the wiper motor on the 67 is real tight. It lays almost on top of the valve cover. The 68 and 69 have a different type wiper motor that has more clearance. You do not need the valve cover with the indention. I think those are for the Corvettes of that time period. I would like to put a set of the Comp Cam Magnum series roller tip rocker arms on mine. They have a little higher ratio lift and should work under the stock valve cover.

Scott get the Pro Magnum roller rockers... They will fit with the 5/16 corker gaskets.
