Clarification to GT6 valve assistance

[EISANDIEGO@aol.com]

I misunderstood the situation with the heads and valves. Still somewhat
confused. I thought the car had the early head, I have subsequently been told
that is not the case, but it apparently not the same head as is typically on
1973 GT6s. Is there a good reference out there that would help me learn more
about these type of engine and vehicle differences ?
