Ok so I was thinking just now about the different engine lines we've had...

A's were all SOHC from what I've seen.
B's are all DOHC except the B20A3 Prelude motor that's SOHC dual-carb'd
C's are SOHC except the NSX motors which of course are DOHC
D's are SOHC except the D16A1/ DOHC ZC
F's are mostly SOHC except the F20B and the S2k motors (how are they even F??)
H's are all DOHC are they not? never seen a SOHC H-series...
J's are SOHC from the ones I've seen
K's are DOHC aren't they all?
R's are SOHC so far right?

Anyways, the bold one is the question I'm most concerned with. Can anybody confirm that there are no SOHC H-series?
