Need valve train advice 318...

so im in the process of putting my 318 together(pis coming soon)..i want to make sure i have all my parts first so im not leaving it half done..or at least have most things done to put heads and valve train together..

first question..i called lunati..they recommended cam 60441..which im sure im going to go with..im buying cam and lifters from them...they said i need springs also..my question i just bought a new set of eddy heads ported, 63cc chambers ..the springs look beefy and was wondering if i have to change them or there just selling my springs??

next question i have 273 adjustable rockers..i let them soak in parts wash cleaned up real nice but the adjustment screws are really dam tight..is this normal.note they wernt bolted down but the seemed pretty dam hard..are they junk?im a going to have to spend $400 for crane ones??thanks fabo..

once i have all parts layed out im posting pics and hopefully gathering more advice(first american motor)i do vw for a living big differance)
