Engine runs rough. Plugs and wires are OK. Where can I find a single spring (including retainer & stem lock)? I have found several new complete sets of 16 springs and retainers for about $150.00. Is it worth it or is there an alternative. Only 38,000 miles on the head overhaul. I don't want to have to pull both heads and do everything over again.

Thanks for any help!

You're probably not going to find that exact spring individually.
The KMO-750 spring is virtually identical though.
Just pull out the inner spring damper. I'd reuse the retainer or use a stock piece.

just my .02, but if one broke others might not be far behind?
I’d replace the set. PITA in car, but it can be done w/o pulling heads.

Found New Springs For One Cylinder

At, of all places, Summit. They sold me the intake/exhaust springs for ONE cylinder, plus associated parts. They will be here tomorrow AM. Will change the whole set when it gets warmer. Crane 104227 cam and 1.6 RR's. Thanks for the advice!!!

OP

are you running stock cam and 1:5 rockers...or?
. Crane 104227 cam and 1.6 RR's. Thanks for the advice!!!

...using 1.6 RR with the 227 cam on iron heads...the exhaust lift is high and is known to either start pulling out the pressed in stud or break the spring. People who did run the 227 cam put 1.5 RR on the exhaust side. Yes there were some who got away with it, apparently you didn't

You may be in for a repeat spring failure
