The only way to know you're getting the correct length pushrods is to use a length checker. Measure and then order. You might save yourself some money.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
That is the only way of getting the correct size for rods if you do it any other way you are in trouble and will spend more than you want. Also make sure you are using the correct lifter and the correct way of setting your preload. If you use the wrong lifter, your rod length will be wrong and will make everything run like ****.

I got away with using my 7.4 pushrods on my milled heads but I was extremely close. I'd recommend you go down to the 3.75 though.

Check your wipe pattern, then measure your preload. Your preload will increase more then anything. Probably in the .080-.110 range I bet.
