i just bought a 97' integra b18b head i was hoping it will be a straight bolt on and play but some peeps tell me that i will have to use my intake manifold and distributor and maybe more from my b18a head is this true, and the reason why i bought the head is because two of my spark plugs are stuck in my head plus my DA has about 220,000 miles on it should i get newer stock pistons and rods to because of mileage and/or is is safe putting a new head on a block that has that many miles on it
