also I keep hearing that the ltx's need to breath better on the exhaust side so are steped rockers better like 1.6 intake 1.7 exhaust?

 

they look like nsa rockers to me. the nsa rockers I have have little "washers" on either side of the rollers to keep it in the valve stem end.

 

with nsa rockers I need a guide plate correct anything else needed?
