I have LB manifolds and I went back to a stock starter (previously had a small high torque Hamburger brand). I also installed a stock heat sheild (from Ames) on the stock starter. There does not appear to be any clearence issues and thus far no heat transfer issues. I only went stock due to the fact that this I my goal, to be as close to stock as possible. I found no benefit to the high torque $200 starter vs. a $30 stock unit. JMO
