I brought up the subject of clearance issues with promags on the valve covers on AFR 220s and someone tells me they won't work anyway that ill need offset rockers. Is this true? Ive never heard this before so im a little suprised by it. Will i need offset lifters as well?

 

227's do but you could setup the 220's to need them.

No you wont. This could also be found by looking at their site, calling them, or doing a search.
