i need a decent set of valve covers for my sbf but i need them to clear 1.6 ratio stud mounted roller rockers and clear the throttle linkage on the bbk ssi intake i had a set of ford racing tall valve covers but the throttle catches on the center bolt relief. im trying to choose between the bbk covers and the trick flow covers both claim they will clear roller rockers but the trick flow covers are almost $100 cheeper i just wanna make sure there gunna clear my intake before i pay for them. i also have the 3/8 in plenum spacer just to let you know. any suggestions?
