stock h22s are not good for boost, stock f22 handles boost better than stock h22
if, if i were you i would just upgrade the bottom of the f22

if you going to get an h22 dont boost it unless you build the block, me personally, i would not do the f/h hybrid, cause if not done right it's going to blow fast

if you get the h22 u can use a chipped p28 with an h22 basemap
