Default Flycutting with 241 castings

Will flycutting with unmilled 241 castings be okay if I'll be using 243 castings milled .015ish?

What size cutters should I use with 2.02 and 1.57 valves? Which sponsor rents them out again? How much is it?

Thanks!

It's just as cheap to buy the tool bro.

As for the 241 casting, they have the same valve angle as the 243s. I don't see .015" making any difference at that point.

Go up one size bigger on your cutting tool to be sure. I used a 2 1/16" head to cut my 2.00" intake valves. That should be fine for you too, since that's 2.0625". Didn't need to cut my exhaust side.
