Head Bolt Thread Size?

[benny205mi16 19 1 Cars]

Hello,

One of the head bolt threads in my block is iffy and a bolt will not start in it.

Can anyone confirm the thread size so I can order a tap?

Is it 11 x 1.5?

Thank you

 

Edit, it's a 1.9 mi16

Yes 11 x 1.5

 

You may find though that it's pulled the thread and will need helicoiling. More common as these blocks get older.
