Looking for 360 advice on a budget.

A question for those that said to replace the exhaust rotators with std retainers and locks. I did that on my 360, and they are MUCH further down than the intake retainers. I was going to have different valves installed as I compared them to std retainer valves and the lock grooves were much further down on the valve. Am I safe running them this way? I didn't want to drop a valve. Just something to think about...
