Tunnel ram or no tunnel ram...
This was a lot of work, but the work paid off as this standard port tunnel ram only fell off from peak 5800 to 6800, 60 HP.
Prh told me he tested this same manifold untouched and it was over 120 HP.
It's ugly on the outside but inside it's beautiful.
I love burr finish, my 1st burr finish too.
