F20B DOHC-VTEC cams
I am under the impression that I would be able to grab H22a camshafts, gears, springs, retainers for my F20B. Can anyone confirm this please? Happy Holidays.

Re: F20B DOHC-VTEC cams (99h22ek)
From what I know which isn't much 
the F20B (Blue Top Dohc Vtec) uses a H22A head...with similar cam specs to the JDM H22A Type S and Euro R...The only difference is the valves they are 1mm smaller then a stock H22A so in theory a H22A stock replacement valve would be a 1mm upgrade valve...valve springs, retainers, keepers, cams should be the same specs as an h22...
From rumors the F20B valves (factory) are known to drop under higher RPM conditions...but the bottom end is good for high reving higher rpm due to the better rod stroke ratio...
