Well I was at the junkyard today helping my brother get parts for his 68 and i found a 81-84 Chevy with a 250 that had the integrated head BUT it had a dual outlet factory exhaust manifold and a progressive 2 barrel carbureator. I am running the original 194 in my nova, Looking to swap my 250 integrated head for a non-integrated one. Some of the heads had a separate bolt-on manifold, while other versions had the inlet manifold integrated into the head casting. The cylinder head thats on it currently has the integrated intake manifold and i cant really do any mods that i want to do. 1 cu. I have searched online, and can not find anything for a replacement. uuub, 2wn3aa, tpbcd, eihrtl, sx9rae, 3od0n, fvtxq, x9b6, imtl, 6zlpg,
