valves

[stevo716]

are the b series vtec valves same design as the b18 non vtec ones?
cuz i wanna put bigger valves in, but only ones i found are .5mm bigger.
while the vtec ones are 2mm bigger standard on intake already, so i cud use one of those, all dependin if they are the same design just bigger
thanks

Good person to talk to would be Adrian/TODA AU.

I know for B-series VTEC engines he suggests pretty much never increasing the size of valves and has stated that he has used OEM valves in most of his builds. Not sure if this applies to the non-VTEC engines, but anyway it might not be necessary.

The valves I'm using are Jun 0.5mm oversized, which is large enough. 2mm sounds a bit extreme I think man, I'm not sure it would be a good idea.

did lil more research and there not the same diff stem width and length
found some 1mm oversize ferrers, might go with them see how i go.
