i just bought a pair os ported E7 heads with new valves and new springs and with brand new 1.6 rockers. but i dont know of any thunderbird people having 1.6 rockers. will they work?
1.6 rockers are stock.
yea the stock ratio is 1.6, unless they have 1.6 roller rockers on them which would be ideal.
yeah, they are brand new ford racing 1.6 roller rockers
then you will be fine, friction reduction is always a good thing, just no added lift with say 1.7 rockers.
