*I would suggest bagging the Helicoil idea all together and install SB Chevy rocker studs instead. Got this tip from Tim @DOA as well as Ted-Engnbldr. Ted sent me up 4 of the studs with nuts, I retapped the stripped holes to 7/16", applied a little sealer to the threads as insurance and was done in less than 30 minutes doing 2 holes. No problems at all. ~Darin
