What size freeze plugs for a Stage II 4.1L

[TurboV6Sonoma]

The block is a 016 off center Stage II. I need the 4 side freeze plugs. I already have the cam plug.

Thanks in advance

What about dorman 555-077 They are steel 1.5"

The number I gave you was steel also. Probably a difference in the depth of the cup. I think you you may be better off crossing over to brass freeze plugs.Sorry I dont know the number , but they are readly available!! Mike

I like using the steel freeze out plugs on a race engine. They are not as soft as the brass and should stay in place better. Beautiful picture of your engine. Very nice work.

I wont argue either way!! My engine guy likes the brass because they wont rust out and provide tiny pissing streams on race day. I use the steel ones because I have them, and I fill my block with hard block anyway , so its not an issue with mine. Mike

I prefer the deeper ones = more surface area. Getting harder to find.
