will a d15 head fit on any block like my y7?

 

yes.
which d15 head did you have in mind? vtec/non/8v/16v?

 

not sure .. just know its a 16 valve non vtec d15 with a stage 2 port job or some ----

 

hmmmm, what code is on the back of it?

 

your Y7 head has bigger valves than the D15 head.

 

my thoughts exactly... the d15 heads, even with a stage 2 pnp bullshit will suck. Offer him $5, or just stick with the y7, it'll flow better. I got my y7 head for $5, it's the going rate for a used d head around here...
