#1 Use A-460 head studs.

#2 Most likely they are 3/8" pushrods and 7/16" rocker studs. Typo on your part?

#3 Yes, they D1VE block has the short cylinder walls. I have used both the 4.300 stroke and the 4.500 stroke crankshafts in short cylinder wall blocks. 4.300" is technically "more better" because it does not pull the pin down so far out of the cylinder bore. Main thing is, make sure and hand sand or champher the bottom of the cylinders so that there are no sharp corners.

#4 In regards to your shrouding, check your exhaust valve clearance carefully. Most of the older Motorsports A-460 heads used either a 1.940" diamter or a 1.900" diameter exhaust valve. Most likely they will hit the cylinder wall (.030" over) as they open.

Hope this helps,
