Just writing ". . . standard AFR springs . . ." and . . ." good to 700 lift . . ." isn't very informative. Besides, you're going to need that specific information at some point.

Pushrods....this is the last component you will purchase. You need to assemble the engine and measure the exact length. It is VITAL that you have correct valvetrain geometry. This measurement needs to be precise since you don't have the leeway like you do with a hydraulic roller setup.
Now that I've experienced the joy of stud-mount rockers with a girdle
I'll be investing in Jesel shaft-mounts over the winter.I don't feel that my combo would really benefit horsepower wise with shaft mounts, its just that its much easier to set lash acurately with shaft mounts, not to mention I can switch back to a set of valve covers that will actually seal. IMO stud girdles are kind of a PITA...or maybe I'm just being a big girl.

IMO it depends on how agressive the cam/spring combination is what should determine whether to go with shaft mounts or not. Stud girdles should just be avoided at all cost. They are a pain in the dick and not worth the hassle. Run some quality 7/16 studs and quality rockers like a HiTech or Crane Gold Racing series with a mild SR and things will be fine. I've been running stud mounts on an engine with at least 10K miles and they are fine. Just had the heads off and looked over and the valve guides checked out fine. The springs have 5lbs less pressure than what was documented when the heads were assembled three years ago.
Basically don't even consider running a girdle. Either run stud mounts with a mild SR application (250 on the seat and ~500 on the nose) or go straight to a shaft mount.

T&Ds are <1000 bucks, that's what I'll be going with. With shaftmounts you can do 1.7s or 1.8s as well, so you don't have to run a crazy small base circle if you want to run some big lift. No reason to stay under .440 lobe 
Hell you can even get Jesels for $899 shipped! Thats likely what I'll be going with. My SR cam is fairly mild, springs are 250lb on the seat, and I've got ARP 7/16 studs and comp pro mags. So I'm sure I'd be fine running without the girdle being as I'm still running the stock PCM. But money permitting, I'm still gonna go for the shaft-mounts. If nothing else, it leaves me room to grow.

go with a solid solid roller valve train (quote brought to u by the department of redundancy department
) and you'll run for a long *** time and be durable.....it IS doable
