more bolt size questions

[canadian]

finally borrowed a block for a mock up of the new motor but don't have any bolts lying around. i just need to have a couple to hold everything together: heads to block, headers, intake to heads, front accessories.

wondering if anybody knows off hand the size/thread of the following bolts:

head to block:
intake to head:
headers:
front accessories:

any help is appreciated. i'll check the manuals tonight and see if i can find anything in them.

Head to Block is coarse 1/2" with a 5/8 head

Intake to head is same as bellhousing and front accesories- 3/8-coarse with a 9/16 or 14mm head

Headers are 1/4"-20 with a 7/16 or 11mm head

All are my best guess, I'm sure someone knows for sure.

Warren, the folks from Holland would love to visit your garage this week.

Here are the right sizes:

Head bolts are 7/16 course (5/8 socket)

Intake bolts are 3/8 course (same as bellhousing and motor mounts)(3/8 socket)

Exhaust (on head side) 3/8 course(stock bolt 9/16 head, headers 7/16 or 3/8 head

All front block holes for accesories are 3/8 course also

thanks for the info. dunno when the holland peeps are going to be able to stop by. this week has been kinda crappy at work. mostly late nights, then go home to bed.

why would they want to see a half torn apart truck that hasn't run in over a year? not much to see, i'd see if ian can roll on by with a functional truck.
