I recently bought a 5.7 with a burned piston, my question is.
The po flycut the stock pistons for the intake valve, however I have to replace one piston. (#7) can I just install it as is and be fine or do I need to try and match the fly cut of the others? I plan on selling this setup and want to be sure I'm being 100% truthful with who ever buys it.

 

What heads and cam is it?

 

Ill be putting stock heads and a stock cam back in it. I bought it as a shortblock minus cam.

 

I would think you don't need fly cut to be exact then.

 

If your replacing everything with stock parts there is no need to flycut.

 

ok good, I was worried about balance and compression difference
