Can anyone suggest a kit? The intake is the M1 4barrel dual plane square bore.

Where did you get that manifold, I was looking everywhere for one.

I bought mine from McMaster-Carr.
I just bought stainless bolts and washers.
I can measure one of them tomorrow.

Congrats on getting the intake, I bought the second one they had left.
 
They are pretty nice, it makes good power right from idle.
It does take a small thermostat.

Also, I drilled and tapped the center 1/8 NPT temp sensor hole to 3/8 npt to run a mechanical gauge. Along with the stock gauge. I think this was on over site by mopar.
 
3/8" x1 1/4" socket heads are nice for access. I just used my old LA arp's.
If you have a TCS near you you can get grade 5's pert cheap by the lb.
 
What heads are you running?
I have eldebrocks on mine and the bolt size is 5/16-18 x 2"
