[Spits] GT6 Head

[Roger Elliott]

Hi,

I have a 68 GT6 Mark 1 with the stepped head.    I see references to 
Early GT6 Mark 1 heads, at the various parts houses.    Is there a 
difference in some of the stepped heads or do the late GT6 Mark 1s have 
the latter full width heads that came on the GT6+?

Thanks,
Roger Elliott
