I understand that the 5016 Harland Sharp's are the bee's knees, but what other options out there maintain the proper geometry for the olds 455? If the HS are obviously the best choice, I will fork out the cash BUT if there is a similar rocker arm in a more economical price range I'd rather go for that.

 

5016's are for Edelbrock heads. They are .050 longer on the valve side for the longer Edelbrock valves.
For a stock head you can use any quality Ford small block rocker.

 

Wait, I asked this question before and didn't get an answer, but will the Crane pedestal ones work in that case? The ones that came stock on the 93-95 Mustang Cobras.

I was planning on running a set of Smitty pro-comps. Same thing?

 

Yes or you can use the Pontiac/Ford stuff. I used a set of aftermarket Pontiac 1.65 Steel rollers on Edins 455. Valve stem contact was perfect.

 

what brand rockers are those?

 

According to Edins build thread they're stainless PRW 1,65 ratio pontiac rockers.
