I'm pretty sure I will need to flycut, but wanted to check with the experts here first.

Here's the set up:
pp ls6 stage 2 64cc 2.05/157 valves unmilled
tsp 233/239 598/603 112+2

If so where can you get the tool to do the flycutting with the rotating assembly in the car.

Thanks

 

I think thunder racing sells the fly cutter tool. But you'll also need a old head for a guide and a right angle drill adaptor.

 

I heard that you can do it with the short block still in the car is this true?
