    Thanks for the info Rob. I'll be running my tomahawk next year I hope,as long as my heads are done. What valve springs are you using?

    How are you guys adjusting the valves. I found there is a difference between setting the intake & exhaust open & closing compared to off the Balancer every 90 degrees. every 90 method is more accurate

    I like the 90° method .always works good for me ..my Scott Brown cam is a tight lash roller for the Tomahawk,guess I will be going zero lash cold ,

    Always the 90-degree method for me as well.
