i bought a fully built b20 head from a friend for a really good deal cuz he lost his job and needed money for bills. an he has a k20 now. but anyway, it has full crower valvetrain an 1mm oversized valves. i have a ls in my coupe now i was gonna put the head on. i was wondering will the b20 head be ok on the stock ls block. i know u can put a stock b20 head on but i wasnt sure about with the oversized valves. and also ill be runnin crower 404 cams with cam gears an a chrome tune.

 

an this will probly be on stock compession

 

LS pistons do not have valve reliefs. You will almost certainly have P2V contact with those cams and OS valves. But don't clay it and find out. Ask strangers on a website.

haha...

in other words... clay it and find out.

also, with crower 404s on stock compression you will probably not make power -- large cams "bleed" compression. clay it, figure out if it will work.. then put together a block that will work best with that head.

 

Put some itr pistons in there, tune it and be done. That will cost you $100.00

 

as long as its a p75 head from the b20 u should be fine, but like other people are saying u will take full advantage of those cams unless u raise the compression trust me

 

thanks to those with the none smartass comments. this is honda-tech, an people do ask questions, thats one reason this site is here. it is the p75 head. im gonna buy another ls block an put some other pistons in it. ls blocks are super cheap.
