Lunatic valve springs frustration!

Thanks for all the responses! I'll take a look at machining costs and those cutters and valve spring mic and see what the better option is! Any advice on what positive valve stem seal to buy and any other things to do to the heads before putting them back on? I didn't want to spend a lot of money into them because I planned on buying some trick flows when I the exchange rate gets better or I become rich! Lol
