Pulled the heads off my car and saw the piston had an ingraving of the intake valve on it. Piston has no cracks on it just the ingrave on it and the valves r not bent at all.Pulling motor out do to no oil pressure. Few things to ask should i replace the pistons and the valves? Flycutting can i use my heads to flycut my piston or do i have to use a junk head for that and y do people use other heads to flycut? And how much should i cut from both valves. I have stock 243 that i will mill .020 or can i mill more since i will flycut,have the g5x3 cam .234 .242 .600/.610 on a 112lsa. any advice will help guys

shoot for 11.7:1 compression if you have regular 93 on pump...figure out what size cc chamber you will need around 59cc, run a cometic .040 and then measure with the heads on and flycut accordingly...or just cut them both .100 and you will be fine...

Just buy the cutters, when you are done with them you can sell them...

Or just rent a set...I rent the lindy tool in head flycutter out, no need to use a junk head with this kind of tool, I used my TFS heads when i did mine...
