Head Bolts

[rc51racer]

I'm looking to verify that I need 18 of the standard head bolts and 3 of the ones that are tapped.

Any body use an ARP part instead?

I found these http://headbolts.com/mopar-l6-fastener.html CHBS-1164 but the set doesn't include the tapped bolts.

Any sources other than the usual vendors? (Midwest and VPW)

I have used the ARP head studs on my 251 engine rebuild. These studs are far better material and clamping forces are better when using them. I have had no problems and yes you need 21 studs. Some of them are a little longer so you can adapt your tubing clamps and filter brackets to them. Hope this link attached works and this is what I bought about 5 years ago..Just measure your existing studs to confirm the correct lengths..

Achiem37, thanks for the info on the head bolts.

I'm going more for an original look, Midwest Military has NOS tapped head bolts so I got 3 of those.

The other 18 I sourced from the engine re-builder, for reference the originals are 7/16”-14NC x 2” 13/16.
