Re: 1969 Ford Industrial 240 valve seals

I looked at the pictures more closely. If that exhaust retainer has the metal cup attached to it and if the valve stem has two grooves - one for a stem seal - then thew umbrella seals are not needed. The combination of the stem O-ring and the metal sleeve is enough stem seal. Or you could use retain...

Re: 1969 Ford Industrial 240 valve seals

Put the valve in the guide. There is a "bootie" that looks like a cellophane sleeve that slips over the end of the valve stem. It acts like a shoe horn to guide the seal past the valve end and keeper groove. Ask your local auto shop if he can give you a couple. There is also a seal driver ...

Re: 100k 4.9 freshen up advice please.

I have had no problems with the stock drive quill on a hi-volume pump. The EFI head is actually less prone to detonation when used with the correct spark schedule. It burns faster resulting in less end gas tendency to knock. But it requires less spark advance (a GOOD THING) than the carbed head.
