What E.T with this set up?

I got '82 stepside shortbed GMC truck and I got this 383ci laying around for some time and a friend of mine which is a drag racer told me bring me your engine and I will rebuild it for you and give you a set up that will blow your mind so I did and lucky me I found a set of brand new AFR 210(1054) heads that I bought for cheap with 1.6 gold rocker arms for less than 1000$ so I went to my friend and told him give me the part numbers or what parts should I order and here is the list of everything I got

Aftermarket balancer and flexplate 0 weight
