I have an 85 Firebird with a 305 Q-Jet. And I was wondering if this motor had roller tipped rockers. And if so can / or do they need to be adjusted? And is the cam hydraulic?

Also I am going to desmog the 305 and play with the timing for next weekend. Its a toy and will only be used at the race track. Any wisdom on taking out the smog garbage?

 

yeah send me everything you have. i need it. jk(kind of)

IIRC they didn't start using the hydraulic rollers until 87 when they switched from 2-1 piecer rear main seals and center bolt valve covers.
