ok dumb questions arise from me every so often. now i thought i read somewhere that all the head castings from the d15b series and d16a6 heads were the same. as the same goes for the d16y series heads. the z6 head falls in the d16a6 head category along with the d15b vtec/non vtec head. now the answer im looking for is can the d16y7 cam be interchanged with the d16a6 cam? im getting the gut feeling and the good old Jack Daniels feeling that this answer is no.

no, different rocker ratios and ramp profile since the cam is offset from the VTEC and nonVTEC design.

Y7 is a VTEC style head, just lacking oil passages.

thank you bone. that is the answer i was looking for. more power to you and more knowledge for me.

Just had to dumb it down to V8 level of knowledge

after i read it i was thinking the same thing with cam hotswaps in chevy 350's that ive done over the years. sucks when not all but very little knowledge from v8's transfer over to the little inline 4's...

It's still an air pump.

How I got great power and mileage from my D15B7, tuned it like a 283 Chevy.

Twice as many cylinders, three times the displacement.

FLAT torque curve on a Honda?
