This is EXACTLY what I needed. Just read your entire build and awesome. One question though. Using your 04 block what did you have to change to make the 08 head work? I read the diy page on heads and from what I understand if you just remove the oil restrictor in the block you can use the newer head. Is this correct? Thanks
