Hoping to share a bit of my recent experience trying out something new for the 350. I had the pleasure of working with Todd at Die Cast Muscle Cars to try out a test set of his legendary exhaust manifold bolts to fit our small block. Even though this is not the buyer/seller feedback, I would like to express that Todd is one heck of a stand up guy and I am looking forward to getting a few more of his items for my GS350. We worked back and forth and eventually landed on a setup that fit the SBB like a glove and gave it the look I, and hopefully most stock guys, are going after. It did involve some very easy cutting on 3 bolts, however the other 11 fit just right. We shared measurements and it is my hope that his supplier is able to fit the need. So who knows.. there may be a set of exhaust manifold bolts here soon.. stay tuned!
