the Ti retainers won't protect you one bit from a real miss shift (for instance going up from 4 to 3 @ wot instead of 5)since those will take em well north of 8K. At which point you'll have serious issues with your rods and pistons...Arp bolts and Ti retainers won't save your long stroke at high revs... no sir.

my 73S was fine with regular springs, and it had a redline of 7300...

Seriously. Waste . off . money.
