I'm just curiouse....
between the LS head and B16 head in height?
do they also share the same cumbustion camber volume (cc)?
since they are both 81mm right?

 

anyone know?????

 

I've never really compared the height of heads but I'm pretty sure (just from experience) that the VTEC heads are all a tad bit taller (Sorry I don't have any actual numbers)... My friend Mike (jdmDXrex) had to cut the hell out of his '88 Rex's hood to clear the B18C, I put this other kids B18B and it cleared fine... Both with the same HaSport mount kit... Just incase you wanted to know... The B16A has a 263mm block deck where as the B16B/B18A/B/B18C/1/5/B20B/Z all have 270mm decks... As for the heads combustion chamber volume the PR3 (B16/ITR) is smaller at 42.70cc as apose to the PR4/P74/75 (LS) at 45.00cc's... Hope this helps and I'll measure a nonVTEC and a VTEC head later today then let ya know... Peace
