New Small Block Stroker Engine Noise

340s the Fel-pro gasket sure is close on the end ports but I don't see any carbon build up from it leaking. Was there any on there? It usually doesn't take any time for burnt gasses to make it's mark. Just by the pic I'd say it was sealing up...for now. But it won't last long with no more gasket than that sealing. Those TTI gaskets may be good but they look just like the style that came with my Hookers and they didn't last long. I put a set of Fel-pro 1413 like yours on it and they are working great. Since they're not matched up well you do need something better. Wish I could recommend something but I don't know of any other good ones. Maybe somebody will chime in on a suggestion.
