Lifter preload...more or less?

I rebuilt my stock 318, rings bearings. Resurfaced the heads, Mr Gasket .025 head gasket, Comp .990 springs and 258 Voodoo cam. I broke it all in using the stock pushrods and some shims as I was concerned the pushrods would be to long. All seemed good after the break in but the valve train was pretty noisy on the passenger side. I took the shims out of that side and it quited down with no ticking on either side. Still not knowing what actual pushrod I really need and want to get the best performance, I got a pushrod checker, removed all the shims and checking 4 corners I come up with an average length pushrod of 7.375. To tha Lunati recommends adding 0.020/0.060 preload, I'm an average gut so I'm thinking 0.040. On the shelf I can find 7.400 which gives 0.025 or 7.425 which gives 0.050...I'm impatient and want to drive.
If I use the stock 7.500 rod I get .125 which seems excessive, but the motor runs pretty good and the spark plugs look nice.
Of course there are other factors to consider, but I'm most interested in hearing the best cases for more or less.
Thanks
