VQ37VHR Stroker Crank in a VQ35HR?

I will be running the VHR 3.7 crank rods and pistons it's a straight drop in.
QUOTE=Juztin;10841179]Question folks,
I've already done the poor mans 37VHR stock crank in a 35HR stroker route. But I'm going to be looking at rebuilding to go to a closed deck block as my car has some overheating issues that we think might be head gasket related. So might as well upgrade the bottom end a little while at it.
The real question is, can I roll with a VQ37VHR stroker kit that has a crank with a 92mm stroke in the 35HR without issue?
The 37VHR stock crank was drop in, but I wonder if the 37VHR stroker cranks (which seem to go above the BC 86.4mm stroke of the 35HR) are compatible with a 35HR?
I'd like to go with a 92mm crank with a 96mm bore to be just about 4.0L.
Any ideas if it's safe to go with a 37VHR 92mm stroker crank, VHR rods (5.886" vs HR 5.974"), and HR pistons and not contact anything?
I've seen a YT vid of a VHR block getting some slight shavings on the cylinder walls on the bottom to clear a BC 4.2x crank (which I'd imagine is a 92mm).
I want to get away from the GTM GT2860RS's and go the GTX3076R (maybe even a GTX3582R if the 4.0L won't take ages to spool); but either way could use the extra displacement to spool those suckers faster, and get more power overall aside from the bump in low end torque.[/QUOTE]

Correction the DE and the HR are different animals, the HR is 8.4mm deck height taller they're slightly defferences 1. the stroke I beleive is 92mm,2.the oil pan is different. the DE is a good engine but the block is weak it could hold 400 whp then you'd have issues on the other hand the HR is much stronger and can withstand excess of 400 whp, I have an 04 DE which I'm rebuilding only replacing the block with an HR and cabrillo rods and pistions,crank
