Post by: NES304 on July 10, 2010, 04:59:35 PM
Where is the best place to get a rebuild kit for an FC motor (with hardened valve stem seals for conversion to unleaded)

Any engine re-conditioner should be able to fit inserts in your head for the exhaust valve and service your head ready to bolt on .....FC427....

It isn't the stem seals that are hardened, it is the valve seats. tetra ethyl lead was added to reduce the wear in the engine of valve seats and to inhibit detonation of the fuel when the compression was raised.

Fuels are quite good now with the removal of the lead, although some high compression engines still suffer a bit. All engines that have valve seats integral with the block / head require the fitment of hardened valve seats to inhibit the wear that they will encounter with the unleaded fuels. If operating on LPG, the same applies.

Thanks for the input guys.
I am looking for a kit to rebuild. I have a spare motor and there is a tafe group wanting to rebuild an early motor so I was going to take em up on it. Just need to know where the best place for the kit is.
