Why is it so hard to get good advice !!???

Just set them to hot spec, I guarentee you it wont be to tight. Then break it in warm it up good and so forth, pull one valve cover and lash that side to hot spec again. Put VC back on and warm it up again, then do other side. Change oil, then run it about 500 miles check them again in the same sequence. After that I wouldnt be afraid of going 1-2000 miles between checks, depending on what the check before tells you.
