Competition 14mm studs vs. 12mm studs

[GO 4LO]

I've heard that the 14mm studs leave too little meat in the block to be reliable at pulling truck boost pressures, but have also heard that the 12mm studs can't provide enough clamping force to hold the head on for these trucks. Any other options available for pullers?

If you were building a truck running 120+psi, what would you use?

I built one that I never intended to see over 100 and I use them(14mm) I ran 12's for a long time with zero issues but I was only at 80 psi, 25 degress and 50/50 on the water.
