Race Head V2 Decompression Valve Option -- V2 Heads are machined and equipped with a decompression valve that eliminates high compression starting resulting in increased service life and reliability.

The decompression valve releases compression in the big bore race engines upon startup so there is no need to start at TDC anymore.

It was designed to eliminate common problems associated with high compression starting such as cracked and broken inner cases, broken kicker shafts etc.

It's also easily accessible with an extended billet knurled end knob. To operate, just push the knob in prior to starting and kick it over nice and easy and that's it!

The V2 Head will come with this option fully installed. 

Professionally machined and manufactured in the USA.

Please Note : This option can be added to any of the performance kits that include the TB V2 Race Head.
