I am in the middle of an engine build using a 2.5 bottom end, i have some ported and polished V2 RA heads, can anybody tell me if these will fit on ok?

i am worried that the HT leads ect off of my car wont fit as they are currently the oval shape (V3 WRX heads) not the square shape.

or would i be better of buying a set of V3/4 STI heads?

Thanks


Ash
