What is a good oil to use when first doing H/C?
 

I will hopefully be installing my new heads and cam within a week or so. I was wondering...what should I use for oil.

I was told to use non synthetic...what weight?

Also....while you are reading...what oil for a new Moser 12 bolt? Non synthetic???? 80w90?



p.s. How long should I wait for my heads before I ask for some money back. Should it matter that they were advertised and quoted only taking 2 weeks...but actually it has been over 2 months..

Sorry just had to ask!!
