I was changing my head gasket and noticed that the no 1 intake valves where real hard to move,After i pulled it all apart i found that it was bent like a banana!!! i used a spare d15z1 rocker shaft thingy .Only diference is that the y1 has two lil holes down the shaft and the z1 has 1 .Does ne one no what these holes are for? the other notch's for oil are the same size and position.

 

Isnt that like the vtec-e head or i could be wrong maybe that may have something to do with it
