intake manifold reversal

Hi can it be done. reverse the manifold on my Rover V8 3.5 ltr so the top hose will come out the back, my rad is in the back and it will be easier to plum in. its on my trike. all the ports line up, any probs if any, thanks.

Bad idea as the water flow will be all wrong in the heads

To expand on

the water travels from the water pump back through the block, up into the heads behind the rear cylinder on each bank, then forwards through the heads to come out into the inlet manifold at the front.

If you reverse the inlet manifold, the water will travel backwards through the block, up into the heads, then straight out into the inlet manifold without cooling the heads at all!

I may be talking shite here, but on my Edelbrock manifold, the rear water ports on the heads are blocked off arent they??
Yes, I'm sure they are. So how does that affect my head cooling?

the head to manifold ports are blocked at the back but the head to block ports are open. There is no water ports on the front of the block to the heads except a small drilling. As Chris said water goes to back of block up into head to front of head then into the manifold/stat. Swap the manifold round you block the front port and open the back ones so no water flows through the heads.

It's so the head castings are identical rather than having handed heads.
