Budget 318 build

Ok so I just spent the last 2 hours reading 318willrun budget build and I have decided I'm gonna go his route with the heads I'm gonna go ahead and pop them off and do a porting job you make it look simple and straight forward I was hesitant to try it but after watching your videos I'm gonna go for it. In the next few weeks or months that I'm working on my suspension,breaks,heads etc I may decide to spend the money on some new slugs we will see where that goes lol. One question about that I found the 814 slugs for 135 and was looking into the rings engine tech has two different sets cast rings for like 30 and moly rings for 50 will either set work with the 814 pistons or do I have to use one or the other and are the molys worth 20 more?
