18 degree valve covers

al wisniewski · 12-12-2008, 08:07 AM

Wonder if I can get some info on 18 degree SBC valve covers. Some of the aftermarket suppliers claim that all SBC valve covers fit all of the heads. Looking for some covers for a 18 degree small block. What fits?

I understand that but the GM book says 15 and 18 degree only?

the same covers for a sbc will fit 15 -18-23- degree heads all are the same pattern . they just have to be tall enough to clear your valvetrain. so any tall sbc cover will fit . i'm using the gm bowtie cast covers on my 15degree stuff. hope that clears it up for you.
