Default B303 and 1.7's ???
I am a newby here...messed with Fords for a long time but had too take a several year break while building and recovering from building my house...

So I am building a motor for my 90 convertible. Stock bottom end with GT40 iron heads. I have a B303 cam and Cobra intake. I have found a set of Cobra roller rockers 1.7 and am wondering if they will work with the B303 and stock pistons..? Clearance problems??

stock pistons your fine, but you'll need to upgrade the springs

a-50's will work and you'll also need the b-50 retainers and a new set of locks
