Those are the comp 918 springs, you might want to consider putting a different valve-spring in there. Also, the I-Beam rods in the Mopar 392 are only rated up to 600-700hp. Upgrade the rod bolts to ARP2000 and that will help.

the arp2000 rod bolts are not too high and new springs are about $200. Considering that a spring failure or rod bolt failure could cause complete engine destruction, I would consider the $500 in purchases.

Awesome build by the way.
