Heads
Our heads are machined out of a solid piece of carbon steel mechanical tubing. Heads are available with 16 or 9 spiral flutes or 12 straight flutes. All of our 11-9 heads and rings are available with the standard 8 TPI V threads or our new 4 TPI ACME threads. When rebuilding a head, the spin flutes and spin lugs are rebuilt or replaced depending on their condition.
On
spiral fluted heads, the flutes are welded up and then ground and
machined to the correct inside diameter. On straight fluted heads,
the flutes can be rebuilt or completely replaced if necessary. If
the threads need to be replaced, we can replace the thread collar
and machine new threads into the new material.
