These are heavy duty valve covers for Cadillac 368, 425, 472 & 500 engines. These valve covers feature an open interior that clears most roller rockers and stud girdles.
This flat top style allows for customization. For example, a design can be painted on or machined into the thick top.
Because these are heavy duty, the thick flange will not warp or tweak. This gives a good seal to the cylinder head.
Uses stock gaskets (not included). We recommend cork or cork composite gaskets.
Covers do not include any holes: $45.00 charge (for EACH hole) drilled.
For each hole required, you will need to order (BL-Holes).
