[bowtietrader]

i installed a E303 cam,double roller timing chain, cobra valve covers, with stock heads.my ?"s are
should i run 1.6 rockers? or 1.7?? will any of them hit the valve cover?? what springs should i run on my heads for this setup?? and where do i get them?? part number or something??

i also have injectors, regulator and more mods too if that matters..im trying to get the car together and lost about the rockers and springs..

any help is appreciated thanks

If you run 1.6 you can run the stock valve springs. If not, buy a set of aftermarket heads or go with thumpers, It'll save you the headache of bending all your pushrods and breaking rockers.

ok i think im goin g to run 1.7"s what do i have to do to run these?? where do i get the aftermarket springs?? p/n?? or anything..
will the 1.7"s hit the valve cover??

Fords were meant to run with 1.6s IMHO. For full rollers, get some taller valve covers. Crane Cams and Trick Flow make good springs.
