I havent been able to find a solid answer on this issue. On DavidGXP's thread he said he had to buy a custom TB adapter to be used with the headers. here is what he had for his adapter.


And the new Valley cover was installed last night along with the heads. finally some real progress.


can you elaborate on the issue with the stock oil pump? i though it would be fine to run with non dod internals.
