Hi Sean! Sorry that I took so long to respond but, I didn't catch the repost. Haven't changed my combo since Norwalk 13'. However, changed the head gaskets over to multi-layed steel and had the heads touched up and installed new valve springs. Car was working good, running a new best of 148 MPH in the summer heat. Was hoping for a new ET best when the Fall air came around but, broke the timing chain the end of July. Bent up a few valves and pushrods. I dropped the pan and tore apart the oiling system and hoping to retrieve missing pieces of timing chain. However, we came up short on pieces. The result was the motor had to come apart. At that point in the year I just had too much going on. I have the motor back now so, it will turn into a winter project. Did you make it to Norwalk this year? I am shooting for Norwalk next year
