Where can I find the deep style brass expansion plugs for a BB cylinder head?
 
I have a Milodon set 34041 that should be arriving today from Summit. I will report back if they arrive.
A reviewer on the Summit site said they were deep, so I am trying them.
 
My order just arrived and the Milodon kit 34041 definitely has the deep, high quality brass plugs that are made in USA. The material even looks thicker than the Dorman plugs that are made in China.

Thank you - does that kit have the plugs for the cylinder heads?
 
No. This is a block kit only. No plugs for the heads. The picture on Summitracing.com is accurate for what you receive with that part number.
 
OK....I may have found something. Two of the plugs on an iron BB head are 1-1/4 inch. The Dorman part number for the deep brass expansion plug is 565-023.
 
Sorry, my earlier suggestion was for the block plugs.

Here's what I just used on my 906 Heads:
Melling is the brand, USA made stamped right on them. Nice, deep thicker ones.
"MPC 16B" and "MPC 18B"
1" and 1 1/4"
 
And here's the Mopar number for the plugs at ends of rocker shafts P5249633. I got 'em from Summit, but they show unavailable. I'm sure you can find 'em somewhere.
