Marketing Phrase .... 'Bolt On A Tenth'

Famous for 'monster size' Primaries.

The '1st' Header Company to develop {1 7/8" Primary Pipes} for a Small-Block Chevrolet.

They were the 'Hot Ticket' for the 1970 NHRA Season, especially at the Indy Nationals, as most of the 'Top' {C/MP ~ D/MP ~ E/MP} Modified Production cars switched to 'OK Kustom Headers'.

'Big Round Tubes' was their trick, to go along with a larger collector.

These Headers produced a 'wicked awesome' loud noise.

Were the popular choice for Corvette Racers, who liked the 'side-mount' style.

One issue with the 'Monster-sized' primary-pipes, they usually hit everything
in the Engine compartment.

They sure 'did not' fit like a Glove.

At one time, the only Header Company who fabricated a Header with;
* 1 7/8" > Primary Pipes
* 3 1/2" > Collector

1970 Price List ......... $175 to $225

Also, were the Header Company who produced units for General Motors. The
'OK Kustom Headers' were the units found in the trunk of the 1967 and 1968
Chevrolet Z-28 Camaro's with the 'DZ Option'.

What makes some of these Header units rare, is that they were 'stamped' with a
General Motors {Part #} on the flange.

As a final note for General Motors, 'OK Kustom Headers' also developed the Headers for the Cosworth Engine.
