Arrow Can you guys help me me figure out what push rod length do I need for my H/C set-up?
Im going to put some TSP Terminator heads (milled to 59cc) on my C5 with a 228/228 .579 .579 114. What push rod length should I be using? IF you guys can help I would appreciate it a lot.

they been milled to 59cc and im using stock GM gaskets. I have 7.350 push rods but dont know if they will work since most people put the 7.4 push rods in when they do H/C.

the only good way to find that out is using a pushrod length checker. and making sure your roller tip is centered on the valve stem/lash cap correctly using marking compound.

What he said. First center geometry, then measure with checker on cam base lobe for p-rod length, add your preload desire onto the length measured and voila.
