These bolts are lazer etched and bar coded . I guess you can do that also . These engs. are backed by a GM warranty . That is unless they have been tampered with as you have already done . , Nowhere have I read that these engs. were perfect . and I will bet that when you get through with it it still will not be perfect . How many laps were on this eng when you decided to open it up ? If you were not planning on modifying the eng. Dont worry about the valve job its under warranty . I think anything you do to the heads to remove metal would be considered decking. and that also is illegal , Regardless of how you think the finish should be . Im sure you can change the timing with the dist. if you want . You seem to know alot about the engs. surley you already have the replacement bolts before you dissambeled the eng.
