Getting ready to put parts on long block----

[72longstepper]

Been over 50 years------------------------------

1. In what order should I put on the timing cover and oil pan.
2. Is it necessary to spot weld oil pump arm to keep it in place?
3. Do you use RTV on every gasket? Was Permatex in my day.

I will be putting an Edlebrock intake on. Would it be safer to install engine with a load leveler system rather than a carb plate (I have both). Front end is off.
ANY help is appreciated.
