Which camshaft?

[weim55]

If you were going to have the engine apart for a complete reseal, while you have the intake off, remove each a lifter one at a time and check the lifter base for condition-wear. Make sure and reinstall the lifter in the same hole as you check each one. If all 16 pass in good condition and you had no valvetrain noise before disassembling I wouldn't change the cam, just leave it alone. There's too much risk with junk aftermarket camshafts and lifters + issues with zinclless oils. You can't beat the quality of those original GM components if they are in good condition.

You've mentioned budget-daily driver a couple times, I wouldn't open this can of worms unless it's absolutely necessary. It's not worth the few extra horsepower for the risk. I speak from a lot of experience with this.......
