Hello,

my 89 Z25's 460 let go on me and i have replaced it with a 532 with aluminum heads. the motor did not come with a cam and im having the hardest time deciding between a roller cam set up or a flat tappet. I have heard horror stories about roller lifters not lasting, push rod angles not being correct and trashing the valve-train, and at the same time i've read horror stories where people are trashing flat tappet cams once a year.

so im really just looking for a couple opinions on what you would do, im completely open at this point as to which way to go flat tappet or roller.

the engine is brand new never started, with roller rockers, eldebrock intake, and will be running an 850 carb (most likely quick fuel).

thanks in advance for any help.
