I'll check on the pix That was actually a compupter ago.
As for the timing covers and cooling.
If you have the correct pump (Cast Iron impeller) with your Timin cover I've rarely had any problems.
Swotching to the 64-68 style is a slight improvment.
However if you use the stamped impeller you may be worse off then before.
The late 69- end of V-8 production covers offer the best flow for the buck.
However, Again I've found that the stamped steel pumps were 99% culprets in overheating and hot running.
