I am rebuilding a L05, 350 TBI. Have the following:

Stock lower end, reman "193" heads, Comp cam springs #981, Comp cam Xtreme 4x4 cam # 12-231-2 with the following specs:

Adv Duration: Intake 250 Exhaust 258

@ .050 Intake 206 Exhaust 214

Valve lift w/1.5 Intake .432 Exhaust .453

Questions are:

What ratio rockers can I use?

Are roller rockers worth the $$$

With a TBI Chips tune, what will the power levels be?
