Budget 318 build

Could i hone the cylinder bores and rering using stock pistons to get a better seal or is that pointless without overboring?
If you can do this by yourself, then yes it would be good. If you haven’t done this, before d leave the honing to a pro or gamble on it.
Back to the timing chain question does the double roller chain fit the same as the stock one it appears to be alot thicker to me does this affect anything during reassembly as far as the timing cover clearance and so on?
Now why would you think that?
Sorry, this question annoys me.
If you have the “How to Hotrod” book, perhaps you should read it again. Your answer will be in the book.
