I know this should be posted in the classifieds but it will never be seen that **** moves so fast, and plus this is an all motor question.

I want to make my B18B head breathe better and am wondering where I can buy these. I only need the intake side, the exhaust side will stay the stock.

 

why oversize? on most application it has no gains.

and you can't run big cams with them.

therefore, useless

 

you can get .5mm over sized ss valves from crower...

oh and if there not worth while then why would vtec heads come with 33mm intake valves?

IMHO one of the reasons that non vtec motors make mean midrange they do is the valve sizing compared to vtec heads. granted they wont flow near as much 8k+ but who cares.. over 8500 non vtec heads basically fall apart anyway soo...

 

Check with Stan at http://www.fast-turbo.com

 

So you guys think that larger valves would kill the midrange on an LS? I thought the LS had such a mid range because of the longer stroke? Anyways some good info so far, any other places that sell flat faced valves?

 

just call tom at 818 335 5316 thats camp1320 hell get what you need

 

im talking about basically the same motor before and after vtec. also dont forget that a vtec engine is on the small cam intill 6k with aftermarket camsso before that our 1 lobe is gonna be ALOT bigger.

 

you dont need oversize

just get normal sized and you will be fine

heres a lil tech article on valves
here=

 

Go with the crower valves
