I found them on Ebay they are made Triton Engineering. I've emailed them and they said they will work on center bolt valve covers.
Anyone have any thoughts on them? They are cheaper than the Comps Cams roller tip rockers. Here's the link to them

They'll work with Centerbolt Valve Cover heads but they are not self-aligning so you will have to use guideplates in the heads.

EDIT: Auction ended. Not a bad price for NEW ones if they are good quality. Never heard of them...

I do have guide plate on my heads already. I've never heard of them either was just wondering if anyone else has and if there any good.

 

I guess you could SEARCH the internet and check Triton's background and Warranty experience...

Good luck.
