I am looking to build a B20B and was wondering if any one makes High compression flat bottom valve’s for the B18LS/B20B motors like they do for the Vtec’s I have looked but have not found any thing.

 

I searched. Found these in two seconds..

Thanks but all of these are dished underneath any that are flat that will raise compression a little?

 

Hmmmm.. Good question im trying to figure out how to search for that.. Search google "not dished high compression b20 valves" ? lol... Just keep looking man and see what you can find. Unless the the honda god posts in this thread with an answer that says "no". lol goodluck worst case scenario call some reputable honda builders and see what they have to say.
