3.0 manifold bolt up to 140 head?

[CamaroMan]

Have a 140 longblock I rebuilt - curious if the newer style manifold will seal up to the earlier type head?

thanks

Ayuh, though the ports might be a different size, it'll run,...

thanks bondo - I was going to put in flat tops and source a newer head but ended up with earlier dish and older head -
