Need new sp heads

Hey guys. I discovered I need new heads. Are the sp heads the same for 1500 and 1600? Or do I need to do some measuring to make sure I am getting the right thing. My parents had my motor rebuilt for me when they bought me the car in high school 13 years ago and I do not remember if it was kept at a 1500 or bumped up to 1600 The ID of the jug is coming out to about 85 mm if that helps

1500 = 83mm pistons
1600 = 85.5mm pistons

I tried finding the stamp on the piston but I cant. So if the id of th jug is measuring 85.5 I have a 1600 correct

And do I have to find heads with the same part number or just make sure it is a single port head with a bore of 94 mm
