Hey guys I'm new here. I have a 48 WD or
I think it's a 48. It has a wd 201 block
but the valve cover says power crater so
I don't know if it simply has the wrong
valve cover or it was rebuilt with wd45
internals at some point. How could I
tell? Also I think it's the 3 inch head
with studs and nuts not bolts, but it
seems I can only find bolts for the later
4 inch head (engine 289000 & up) mine is
WD205326ga. I'm gonna have to pull the
head off bcuz i think it is cracked but
I'll need the right studs. Any help would
be great

You can reuse the studs. 3" head makes it a WD. Hard telling whats been put in it. I've taken apart 3 201 engines that have had a 45 crank and M&W pistons in them. I don't think Allis ever used a head bolt. It was always studs and nuts.

Engines with the tall cylinder head had 5 studs and 10 ?? bolts. When you get the head off, measure the bore (4 inch or 4 1/8") and stroke (4 inch or 4 1/2") to determine what engine it really is. Good luck on the cracked head. I've never seen one crack (yet).

Well I pulled it today and it's not
cracked. Just a bad head gasket leaking
in cylinder 1. Also a bad spot on the
cylinder wall so time for a sleeve and
piston kit.
