Do you typically reuse the existing bolts/screws (not sure which they technically are I guess) from the old valve covers?

The SDS covers come with new hardware.

Very High Quality Parts!
I've recently installed these valve covers (and the induction tube flanges) on my IO-320. Beautifully machined and finished parts, and installation couldn't have been easier.

Thanks for posting the photo Chris. Glad you like them. Look great on there.
As Mike said, we supply with SS Allen head bolts and AN washers.

Here are some pictures of my SDS Aero Billet Valve Covers. I emailed Ross the stars and bars emblem and they laser etched them. Easy and great communication and support. These are on new Superior Millennium steel cylinder assemblies.
These things have a slightly larger flange width than OEM valve covers so I had to trim the aluminum baffles around the footprint of the new covers so they would mate against the cylinder head sealing surface.

Black
We just finished having 2 sets of valve covers anodized and laser etched for two customers yesterday.
Got lots on hand for PV engines, some more AV ones machining next week (finally).
Can anodize in clear, gold, red, black and Navy blue. |

No plans for anything like this. Our AV covers sell about 1/10th as much as PV covers so it would be a money losing proposition for us to design and prototype these.
Sky Dynamics already makes these anyway.
