ok im gettin ready to start puttin together my LS vtec tomorrow but im kinda thrown into a perdicament and wanted to see which one of the following two people prefer. for the ls vtec i have 2 b16 heads that i can use. the first being an OBD0 91 JDM B16A head and the 2nd being an OBD1 94 B16A3 head? this going to be matted to a 95 B18B1 and then be dropped into my 90 crx. does anyone kno of any pros or cons to using a JDM or USDM head? thanks everyone quick responses would be appreciated as im doin this tomorrow. oh yea another thing which would be worth more to keep un-used "as a spare" in the long run. thanks again

 

other than it being a newer head...not much i believe....are the heads stamps both pr3?i know the cams on the obd1 head r better than the ones in the obd0

 

like he said...newer better (most of the time)...

 

go with the newer one, the cams on the obd0 heads are pretty weak.

 

they are both stamped PR3

 

if u want u can just send me tha old b16a head to me..ill take that junk off ur hands....hahaha

 

there should be numbers on the ex side that read somthing like 9l9 or 0l0 and the first is 98-99 head and the other is 2000-01 head

 

well by the vtec solonoid the newer onse has a 30 stamped on it which im assuming is a P30 its year is stamped 9l3 and the other one i kno is jdm beacause it has the older runners not like this one.

 

run the newer one..newer is better...good luck on ur build man
