Looking at putting some heads on an LS1 that already has a cam.
Cam is a 228/232 .603/.609 110lsa
Heads are Patriot stage 2 LS6's, milled to 59cc.
First, are the PTV clearances ok, or will I be putting a valve through a piston?
Second, what pushrod length do I need?
Third, can I use 1.75 rocker arms on this head/cam combination, without flycutting? (turns into a ..620/.627 lift)
Thanks in advance for the help...

You need to measure.
Second, what pushrod length do I need?
You need to measure. There are a lot of variables and the pushrods are the last thing you should order. Buy an adjustable pushrod instead.
Third, can I use 1.75 rocker arms on this head/cam combination, without flycutting? (turns into a ..620/.627 lift)
Max lift occurs with the piston down the cylinder so it really isn't major a player in PTV.
