ive done the search, read all the post. and in mike323's thread it came down to the simple question,
is it the pistons that lower the comp or the block?

i guess what im asking is, are they the same blocks with different pistons?

 

The blocks are the same, therefore the SOHC pistons lower your static compression ratio.

Also, I beleive the DOHC block has oil squirters whereas the SOHC doesn't. Can someone confirm this.

 

the dohc does have oil squirters. i can take a picture if your quriouse to see what they look like.
