Looking for some sbc logs, snails or O/T headers.
Are you running tall valve covers?
I have some Hallcraft Marine logs and may be able to scare up some risers but they will not fit taller than stock valve covers because they are up shots....I was going to use then on the Southwind, but they would not fit the motor we had....They are a solid 8 out of 10 as far as condition, but I don't know if I have riser yet (I will go scrounge if they will fit your stuff

)..
I will make you a deal you can't refuse.

I also have some headers, but I am in to them too far and need to get a bunch of money for them if I were to sell..
