Custom oil dipstick mismarked 6qt

MRLPerformance 360 with Summit Racing G3536 oil pan. I have documentation that it takes 5 quart oil capacity like typical Mopar small blocks. It has a locking engine oil dipstick that looks like from Masta Performance. 5 quarts brings the level to the low mark. Where it was marked full is actually 6 quarts.

I called Masta Performance and they want $55 for a new dip stick. Probably just remark the dipstick.

Just confirming 5 quart oil capacity? What to use to remark the dipstick?
