Product Description

 Universal Fit, .502" O.D. Guides

Manganese Bronze Valve Guides, 11/32" X 2.375" Long

Order quantity one to receive 16 bronze guides @ the rate of $2.99 each ($47.84 / 16)


These are one of common lengths used in many domestic V8 engines. SB Ford, 351C, 351/400M, etc.

.502" Outside diameter guides are the standard of the industry.

This type of guide is used in heads which have "integral" guides. This means the guides are part of the casting and are not removable.

Heads are set up in a "Seat and Guide Machine" and each guide is core drilled, then reamed to .500".

Guides are then pressed into place and any extra material is spot faced to match the casting.

After the guides are installed, it's standard procedure to us to use a .500" valve seal cutter to remove any old remaining guide material from the guide on the spring spring side of the head so .500" Positive seals could be installed, as well as any remaining thin-wall iron material can be removed.

If needed, guide inside diameters are then fitted by either reaming or honing w/ Sunnen tooling.

Looking for something different? Special sizes are available on a special order basis.

TECH NOTE: Aluminum heads always have some form of guide inserts. This type of guide is not intended for such heads. Applications w/ aluminum heads normally use replacement guides in the same style as installed from the factory. If you're looking for replacements for aluminum heads, write to us and we'll advise. This site is in a constant state of construction, we offer much more then what is shown here.
