Need some of these ugggleee things

I can call my younger son and see if he has any around his shop for you.
He races dirt track and uses these 305 heads some time because of the small jernals in the heads.
I will call him today at noon and find out.
I do have a slant exhaust if this would help out.

I keep this covered with a tarp when it rains
That is a complete 440 motor on the pallet and I keep them sprayed down with blaster.
