Last I checked Jay had a very liberal almost non existent rule plan basically only banning national Motors of any age. So you should fall in there. I remember them 820's one liked to killed me.
My way of thinking is "KEEP THEM PORTS STOCK AS CAST" and everything should fall in place. A very easy check with a bore scope.
Other easy bore scope checks would be
1. Cranks
2.Rods
3.Piston crowns
The new bore scopes will even take a pic and put it on your computer, then it is simply as what the little boy told the little girl.
4. Some people just are way over concerned about engine modifications.
