Header Gaskets Round Or Square, what brand have you had luck with - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys,

I have a 1972 C10 with a rebuilt 5.7 350, it has headers on it and I have a leak at the manifold that is driving me nuts, I have new custom duals with Flowmaster 40's and it sounds like a crappy pre-resto beater lol.

My question is does my 350 have square or round exhaust ports, and what type or brand have you had luck with? I tried to search for an answer but there were a ton of answers but none seemed the same.

Does anyone sell Grade 8 header bolts that you know of? I have broken some on my 427, and it was a nightmare. I would prefer to put grade 8's in now.
