Re: Oil Foul

Have you performed a 'dry/wet' compression test to see if it is worn rings or guides?
Is it more than one cylinder that is fowling?

There are several things that will cause plugs to fowl - worn bores or worn/broken rings allowing excess oil to get to chamber, worn guides allowing oil to be drawn into the port on the intake cycle and bad/missing/worn/cracked intake valve stem seals allowing oil into the guides even though they are not worn beyond the serviceable point.
If it is the last of these problems (worn/bad valve seals) then you can sometimes extend the service life of the motor by installing new GM style seals at the Retainer or, even better, by installing "umbrella" style seals on the intake valve guides.
There are several aftermarket seals available that will install on the guide without any machining (my favorite are the early 'Vega' seals...) required and you could do this in your driveway in an afternoon to see what results you get.
GM actually issued a service bulletin back in the 70's about plug fowling due to excess wear of the #5 & 7 intake guides on SBC's with the recommended fix being installation of umbrella seals v.s. the retainer/stem OEM type to remidy this.

This may be a quick-easy-cheap remidy for you to try before you decide how to build your next motor.

Re: Oil Foul

Doubt it is the "valves" not seated. There is an off chance the rings in those two cylinders could be not seated or leaking by. A 'wet'* compression test would show that. How many miles/hours are on this engine?
Could be the two paired valve seals in that area are allowing excess oil by. Is you brather directly above them and is it baffled. The type of baffle used in that area can allow oil to drip back directly onto the valve springs for the intakes and overwelm the GM oil control seal at the retainer. In that case installing a couple of umbrella type seals on those two intake shafts will stop the oil fowling. This was common on mid-to-high mileage SB's and installing umbrella seals was a stop-gap measure to correct it.

* 'wet' compression is the use of an oil squirt or two into the cylinder before the compression test to see if it seals the ring area and raises the compression readings - this is an indication that the problem is the rings v.s. the valves.
Note - do a 'dry' test (no oil) test first to get a baseline reading for the compression in each cylinder.
Comparing the compression test numbers can tell you where the problem may be.

Hope this helps;
John

ps: Oh - Jim & "your 'blowby'" - nah... laying off the mexican food may help a little with that though...
btw - if you keep up with those kinda questions your gonna get a new nickname on here - Mr. Toot
