On my small blocks I put my figure over the stinger but on my big blocks, which right now the only one I have, running is my Savage so I put their stop on that rubs on the flywheel because the big blocks get so much hotter. All so on a Savage getting to the flywheel is not easy! You touch my Savage pipe at full temperature it will burn you I know! Not sure how I will do it on my buggy with a big block until I get it running.
