What rockers are these??? Have pic.

Hey guys. I bought these roller rockers off of a friend for 100.00. They were used for about 200 miles, then removed. I was told they are 1.6 ratio, but I think they might be 1.7s as they are big. They have the letter/numbers "F72" on the top of each rocker, right before the tip, and they come with black guides. I have a pic at the link in my sig, just look for the big blue roller rockers. Please help me ID them. Thanks!

That's what I assumed. My mechanic originally purchased them, never used them, then sold them to his friend. That friend ran them in his car for 200 miles, then removed them for 1.6s and sold them to me for 100.00 through my mechanic. My mechanic swears that he remembers them as 1.6s, but I think they are the 1.7s, only because of the mark. They are in great shape, no visible wear or anything. The only mark on them is "F72" though, so I just want to know what I have.

I just did a google search of FRPP 1.72 rockers, and they have the mark "1.72F" behind the main trunion area, so maybe these are older versions? I know they were purchased a long time ago...

Also, if they are 1.7s, will they fit under stock valve covers with the baffles removed, or do I need taller covers?
