I mixed my cams , springs , retainers , valves from 2 h22 engine in a box ...

1 kit is from my h22a4 engine and the other kit is from a h22 euro-r red top .

Everything looks the same to me , im lost.

How can i know which is which ?

thanks

 

Well I would think that the only difference between the two would be that the springs for the euro r would be stiffer (stronger) but I don't think you could tell with your hands. the valves and retainer should be the same and the cams, the lobes are different sizes you should just look carefully at each piece and try and find out which ones match each other. good luck

 

H22A7 (Euro R) came with Type-S cams, I believe.
