Thank you all. Trying to keep the 350 alive for now while I do more chasis/body work this year with plans on swapping in a carbed 4.3/700r4 set up to deal with the ever rising cost of gas (but let's not get started on that topic -grrrr).
I've got a valve issue of some sort on cycl 6 (carbon fouled plug, lifter noise/& dollar bill/tail pipe... well the darn thing tried to swollow my dollar. Even found that the push rod has a very slight bow in it). Thoughts?
Can you tell which size valves are in there without yanking the head? casting marks/numbers? If it's the desireable heads I'll investigate getting it/them up and running. However, if it can be determined (without yanking head) that it's the less desirable head, I'll keep my eye open for a set of used performers (I'm putting on a wieand 8000 intake in place of the cast 4bbl manifold which is pretty close to the performer intake. I figure to rebuild the rochester 4mv and then call it good for this motor until I do the swap).
As always, thanks for your help folks.
