I was wanting to get my rappy's head ported and polished; how extensive should i go? What are the main things to do, to it? I have a 11:1 piston and a hotcam, and exhaust done already. When you take it to the machine shop do they need the valves or what?

At the shop i selected its $60 per hr. So whats necessary?

Not trying to sound off kilter here but if the shop you're going to have do it charges 60 bucks an hour, THEY should be telling YOU what is necessary. Ask them what kind of flow numbers the head will produce when finished....should be interesting to see what they say to that.

After i get this done will there be jetting issues?

If it is done correctly you will have to rejet.

Will i just need to change my mains or will the others need changed also?
