Burn that rubber!:thumbsup:Beanhead, thank you for the response, it’s much appreciated. I have the rockers and shafts off now and will shim everything again. What a pain to get everything lined up with the pushrods and the lifters pumped up. I’m going with your advice and hopefully that quiets the motor. Your right, the motor is very strong, even though I’m taking it easy on it for a few hundred miles it still easily breaks loose my 265 tires, like I had bicycle tires out back instead.
