What size freeze plugs for the TTA heads?

[Jan Larsson]

Thought I got all the freeze plugs I needed but just noticed when I put them all back in the block I'm missing the ones that go in the heads ... anyone know the correct size?

Looks like it might be 1 1/4" size plugs for the cylinder heads ... anyone know for sure?

 

[Jan Larsson]

Any one can confirm the size? Need to order some ...

Might be 1 1/8" .... not sure

Thx Dan, need to get some ordered as soon as possible ... heads no good without them

Great, many thanks. Is that a regular deep one or a more shallow cup? Can you measure the dept if possible?

Depth looks to be 3/8's of an inch
