would this raise my Rod-to-Stroke ratio..?if yes...would I be able to Rev it higher than with the stock H22 crank/rod's..?

h22a is 90.7mm, f20b i believe is 88mm someone correct me if i'm wrong just find the rod length it should be under the H/F specs on here theres a bad *** write up on all of the internals specs of these motors

Sorry I asked the wrong question I meant Rod-to Stroke..

 

yes it would raise your rod to stroke ratio h22a is 5.633/3.571=1.58:1, f20b i believe is approx 5.709/3.464=1.65:1 which will let you hang around the 9000 rpm range more comfortably but your powerband will be shorter in my opinion the h22a offers the best of both for torque and reliability but nothing wrong with the f20 combo either i will be adding a h22a crank to my f23 block soon for my g23 vtec combo...
