My local Pontiac engine guy was also pointing out that the "old" stock Pontiac rods had a grove cut in the crank-end that would splash & squirt a lot of oil around the cam area.
Not sure how much of that corresponded to longer cam life, but I am sure it certainly did not hurt.
After struggling with this issue previously, I am very hesitant to go flat tappet on my new build, but my car budget is pulling me in that direction, as I do have a very long xmas list for the 73...
I was discussing this with Dave at SD last year as well, and he mentioned they had very good results with the Crower solid flat lifters with the Cool Face design. This is what I am currently leaning towards until I spring for a roller and aluminum heads again.
