Economical replacement rocker arm set?

I guess you have to use them just because he gave em to you for ... free?

:)
Yep, awesome dude. We thought this was headed toward the need for adjustables and he stepped right up. Wouldn't even take money for shipping. Now I have to decide if I use them or not. Part of me says to leave good enough alone. The other part says, adjustable would be cool...I guess.

I'm not sure what advantage they give me over properly functioning non adjustable rockers. 50hp maybe ?....
