WTB block off plugs for dual plug hemi head

[Hemi T/A]

I recently bought a set of NOS Mopar Performance Hemi heads with provisions for dual spark plugs. One head came with 4 block-off plugs and one head didn't have any block off plugs included and Im only going to run one plug per cylinder , so Im in need of 4 block off plugs . if anyone has 4 ( or 8 ) and would part with them please let me know . thanks
