Cam/Tappet compatibility

[diomed]

Hello,

I have a couple questions about the compatibility of cams and tappets. When ordering parts, I assumed everything would just work but searching FordBarn threads got me confused.

I purchased a set of Colony double-lock tappets and also a set of Brattons house brand single lock tappets. I tried to use the Brattons single lock and they were so tight that I was finding it very difficult to adjust them without rounding the heads off the adjusting bolt. Even though the double-lock is more cumbersome, I think I'd like to use them

Extra info, the base diameter on the Colony double-locks is .995 and the Brattons single lock is 1.15. The Colonys seem a bit small, thats pretty much the reason for this post. I'd rather buy a new cam now than wipe out what I have due to incompatibility

Could somebody take a look at the pictures and help A) Identify the cam, and B) tell me definitively if the double-lock tappets will work with my cam







Thank you,
