Need Help from a 426 HEMI owner in Edmonton

Hes at Castrol Raceway. He blew them out last night and was hoping to fine a set in Edmonton this morning so he can test today. He came down from Fort Mac and only got one pass in...

I don't know but Red Deer might be a bit far. I'm not familiar with the area...

Its a 478 Hemi, 426 heads so I think the header gaskets are the same as stock.
