I will be at the GS Nationals early Thursday morning 10-25-2019. I have all the tools. If you "KNOW WHAT YOU ARE DOING" with Comp Cam 280-12 valve spring installs and can perform the install in a reasonable ammount of time for me to test and tune, I need you there.. I have 24 keepers, valves, and the tool to compress the springs. PM me if you are ready to help me compete.This is a stock 109 block. Not trying to float valves or wipe cam lobes. Just want to have fun with our fellow GN folks. PM for info.
