I'm looking into buying a built shortblock for my 06 revup but I don't know if the revup heads will bolt up to a non-revup block. Are the non-revup and revup blocks exactly the same? Is the only difference the heads?

You cant swap heads as far as i know. The deck angle is different to the timing cover would fit right.

I'm in this dillema as well, bump for more answers! Few people reputable tell me that I can do it, but some people (not so reputable but still) say i can not

You can use your rev up heads with any block you just cant change from revup heads to non rev up heads.

So you're saying I can be okay in my dillema and use my current REVUP head and use the BUILT nonrevup block right? I just can not use nonrevup block + nonrevup HEAD in my revup car. correct? Sorry for all the "rev"s haha

The blocks are identical, only the heads are different.

ECUs are different too.

yes you can. the regular heads have the provisions for the exhaust cam timing sensors. you just have to open up the holes.
