Frequently Asked Questions

What does +0.006 in mean?

The bore is 0.006 in oversize to accommodate a new exhaust valve stem or correct wear in a high-mileage head.

Do I need both intake and exhaust guides?

Check your head — some rebuilds need one, some need both. Order intake and exhaust guides separately as needed.

Will this fit my 1984+ Shovelhead?

No — this guide is for 1978–1983 Shovelhead engines only. Later models use different bore specifications.

Is installation difficult?

Valve guide installation requires removing the old guide and pressing in the new one. Most shops handle this as part of a top-end rebuild.
