Chris,
The FE is one tough motor because of its design and centerline positioning of the crankshaft. It''s been my experience though if there''s one weak link in the FE it''s the rocker shaft area. From my own experience I''ve broke more then one shaft with cams no larger then 244 @ .050 w/.560 lift and were never past 6000 rpm, some were less cam then that. For me it''s always been over #4 and #8 cylinders.
The aluminum stands will tend to walk and it''s only compounded further by the springs separating the rockers. Not to say it will happen to you, but if it does you''ll wish you spent some extra money there if you need to rebuild the motor. I opt for a complete Dove set up now which includes heavy shafts, billet aluminum stands, solid rocker spacers, roller rockers, and rocker shaft end supports. They''re very pricey, but for the way mine is set up they''re well worth it.
There are however other options that are cheaper, I believe it''s only a few hundred dollars. They''re not as strong as a Dove set up, but much more so then stock and should be fine for your application. Call Summit Racing, I think they sell a better shaft and stand and also have the solid spacers. You''ve already got the good rockers and you can always get end supports in the future.
Just my "costly" experience
Hope it helps
Ken
