For stock rods , it is better to retain the press fit design. Aftermarket rods are designed for a bushing in the small end.
The 981 springs from comp will swim around on the stock valve guide boss. It is best to control the spring on top and bottom for better valve control. Look up videos on youtube for spintron valve springs. My springs work great.
Does ARP make a press fit setup to use with these stock rods? Or should I just keep the stock bolts and not waste my time with aftermarket?
