i got jun 3', jun spring, portflow retainters, spoon headgasket, arp headbolts. all going in my 96 JDM specR Is there anything else i should change out while im at it? valves? are they necessary for an allmotor application? thanks mike

 

cam gears, you're gonna have to be able to tune'm.

 

change to valves while you're at it. its cheap & most important of all, you'd need it to play safe. build your bottom end too.
