i have decided to keep my car some what orignal. meaning i am gonna keep the orignal 200ci engine. but i am gonna have it bored out. the shop im going to will bore it .030 and hone it for $175. hot tank for $50. how much can i bore the engine. i was looking on the ford 6 page and the sell rings for .080 how much would i gain by boreing it more then .030. i am also going to have a 3 angle valve job and should i replace the valves and seats and springs?
