Slant 6 225 Headers for sale

well take a peek at the bypass hose that goes from the cylinder head to the water pump on a 225 and a 198 I could be wrong but back in the 80's i had a 69 valiant with 225 and the clifford long tubes when I installed a 198 there were issues with the headers, The Point being that these headers were built for a late a body and won't fit an early a body

Understood Waggin, just emphasizing that the 225 and 198 are outwardly physically the same dimensions. By pass hoses are the same 225 and 198. Bypass hose is alot shorter on the 170 because it is a short deck engine (approx 1 inch) compared to the tall deck 198/225 (common block).
