What pushrod length?

I need to know what pushrod length I need. Cam is a 02-04 ZO6 and heads are stock 72cc. I have a pushrod checker and it looks to say I need a 7.400, but want some other opinions. Thanks

7.400" makes sense. The stock pushrod length is 7.385" gauge length and the 02-04 Z06 cam has a smaller base circle (0.025" if I recall correctly) so the 7.400" would nominally put you 0.010" more than the stock setup.
