I think you need taller valve covers to run the 1.6s.

 

could i expect a nice gain though? Do you know what brand they are?

 

stock rockers are 1.6 but dont have a roller tip... most pople go with 1.7 that will open the valve more(so more gas/air more hp),,,,, so the only gains with the rocks that you have posted would be the roller tip( so a little) if later down the line you buy higher lift cam those would be good the buy.

as far as the brand?? i dont know the only blue rocker i've seem are Mopar Performance

but they don't look like that

 

i found this. not sure if true or not.

The rocker kit is Hughes 1536-16. The rockers are blue, and have 'PEP' and 'RR350A1.6' etched into them. I have a pic if anyone wants to see it. The pushrods are Hughes PN 5260.
