243 heads LS2 and LS6 - how to tell the diff?
Ok i bought a new never run set of 243 casting heads off e-bay. Is there a easy way to tell if they are LS2 or LS6? from what i understand the LS6 had longer hollow stem intake and sodium filled exhaust for less weight - is there any way to tell which valves are in them ? is teardown required? of course im hoping what i have is the LS6 variety but if not ill get over that too , does anybody offer CNC porting on our own castings? or would a sanding roll cleanup of any rough edges be sufficient? just would like a strong running street motor. any help appreciated !

I know i have the ls2 variant but don't know how to tell the difference, thought they were the same, they are on the shelf so i can look at them it someone chimes in w what to look at. Mine are waiting to go to GTP for cnc and porting before going on. Just waiting for Craig to get the machine in the manufacture keeps saying it on the way
