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.

 

+1

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.
