Happy ending, right. Er, wrong. So I ordered new springs since my old ones were so old I thought they were maybe original. New springs, still no tick. But not much later she’s running rough. Two wiped lobes on the cam (actually they never ticked but it ran rough). Then I dropped a valve. That set me way back.
So since I wasn’t planning on having to buy heads I used this 703 cam because I had it and it “should” work. But the tick makes me nervous and I feel the cam is not the best choice. I would be more comfortable replacing it but would want to be pretty sure what I got instead was more suitable.

That's exactly where I was so I went conservative on the cam after the bad new 703 with the lifters that came with it. .
Sure wasn't going with anything like what didn't work.
I'm really happy with 2157 Edelbrock cam and the lifters that came with it.
The engine runs smooth, quiet(a blessing) and has great power from 0 to 100.
Have to be very careful with it now because you can break em loose in any gear.
I do have to use two bottles of 108 octane booster per tank with 93 octane to stay away from spark knock.
That's after I timed it by ear. It pinged bad setting it with the light. lol
