I have a v8 northstar engine from a 05 SRX. I am looking to find the dimension of the head bolt holes. I want the measurement from the center of one head bolt to the other.

I drew this picture of the measurements I want. The measurements in red are what im looking for center hole to center hole. I believe the measurement from the top head bolt to the bottom one shold be about 3.3" but I am not sure
