iirc the revups and HR's can interchange cams. valvetrain has been used as well. i would think that if they can be used then the revup would be the likely candidate. i have read somewhere that you can put revup heads on a de with little mod, so who knows.
i just can't imagine them flowing that much better, and if all you are doing it for are the cams/valvetrain there are better options out there.

do the HR heads have cvtc on intake and exhaust? if not then you should be abe to. the reason you can do revup onto a non-revup is that you wouldnt be able to control the exhaust cam timing with a non-revup ECU, but if the HR doesnt have cvtc on exhaust then i think it would work. the only problem is that you would need a new intake, since the ports on the HR head are square where as the LIM of the de is oval port, so you would need an LIM with square ports to go with your new heads

2. The square port thing only applies to where the LIM meets the UIM. The intake ports on the HR head have the same exact shape as the non-HR heads.
3. One could then use the L32 altima LIM and plenum.
Might have to use an L32 inner timing cover as well depending on the bolt pattern...

BTW, the OP has a maxima.

Don't waste your money on a port and polish. VQ heads (regardless of what engine model) flow AWESOME. All you need is cams unless you are doing a really crazy setup (over 800whp).

thinking out loud:
wouldnt throttle position want to be used to trigger this ctvc in addition to rpm. seems kinda a crude way to control such and advanced feature
