Whats different about the block? I was under the impression all year blocks, 02-10 are interchangeable.

02-05 had different oiling sys. than 06-10

The 03-05 had a oil pressure jet in the block and 06 -present do not. Just pop out the oil pressure jet and replace with a new rocker shaft 06-present and all is well. Or if you want to go backwards just pop in a RR Oil jet for a older 02-5 rocker shaft.

What ya thinking bro? Did I miss something?
I personally would go without the oil pressure jet and the Newer Drilled out Rocker shaft.
Oh crap I was talking about SCed blocks.
Not the NA 02 block!
Scratch everything Mike as I am not sure about the NA block.

I was thinking if it really I can remove the oil pressure jet from my conversion
