Inliners International Forums General Discussion Hi Performance New valve cover coming soon! 250 292

Vanherk,
I am working on it. Rest assured, it will be right when done.

Hey vanherk, I have my patterns finished but we have been dealt some crazy winter weather here in the south that has kept me from making any castings this month. As soon as the weather eases up I will have the opportunity to make some. I will have a finned "no-name" 2 piece and a finned "brand name" 2 piece available.
With so many fleas trying to jump on the same dog, there should be plenty of product out there.

I have more to update on my valve cover.

It is now made with a variety of finishes.

As cast (exterior is not blasted or sanded)
Blasted
Polished
Powder Coated

Other choices
Polished tips

Another variation is a NON Finned or smooth .

Here is a video that shows fitment with roller rockers and comparison of Clifford and Offenhauser valve covers.

Nice job Tom.

Hey Tom! Just as an FYI, Your valve cover may have some issues with certain guide plates. Larry's Power is putting the final touches on my 292 and had clearance issues with the guide plates. I think the plates are from Crower.
The fix is simple enough . They had to clip the corners on the outside most plates and I think they may still have to remove some material from the inside of the valve cover.

Stan,
Sorry to hear of the conflict. The good news is, I am on revision 3 of the cover.
Rev 1 is what you have and was of approx. the first 30 valve covers.
Rev 2 open the inside a for greater clearance for springs/ rockers.
Rev 3 removed some of the mounting pad for the internal baffle. This was to make a better/ cleaner casting.

Your engine is looking nice.

Rev 4 would be good so we could mount shaft mounted rocker arms.
Having enough room on the ends of the cover for clearance.

Tom,
Nice video,Have a question how does the Precision valve cover measure up against the other 3 valve covers?

The PES cover needs a spacer because it is more like 2v8 covers together.

Larry is right. The PES is a BIG valve cover. It can hold a stud girdle. The adaptor is needed to mate the valve cover to the head. I sell them as a kit.

It is like having 2 BBChevy vlave covers welded together. It seals with a rubber oring for the gasket.

Here is a video showing the machining of the bolt pattern on my CNC.

The adaptor plate is like 1in. thick the valve cover it-self is short in height. And It is square and UGLY as All Heck. I know a guy who has one. So me personaly I wouldn't give a wooden nickel for one.
