rocker arm switch

[Frankensteinz2]

Hey guys,

I recently bought some resurfaced rockers to replace my old ones as i am putting in a different cam, still stock however my old one had a worn lobe so i figured new cam i better get some refreshed rockers. My question is about the new rockers, they look a little different and I am concerned about the rocker arm geometry being different. The person I bought them from on ebay stated they were out of a 240z. I have attached some pictures. Can you tell me what you think?

Thanks Frankie

The black is my old, and the silver are the resurfaced rockers.
