purchase a chilton manuel for it. makes it easier. or smaal block 350 book.but first get rid of everything in front of the motor.fan,alternator,a/c powersteering etc. then remove both mounting brackets that mounted all of those components. remove intake manifold label all vacume hoses so you know where they go and unplug all wires. label them if your not sure but they pretty much only go to where they're supposed to.take off valve covers and remove rocker arms and push rods. if reusing them make sure you label where they came out of. remove head bolts inside and outside of head then a little bit of elbow grease or pry bar and off comes the head.use new bolts when installing with thread locker. clean block as best as possible try not to get anything in the piston ports and use a tap to get old thread locker out of block where the head bolts go.when installing get a chilton manuel so you know all torque specs and and how to proberly lubricate components. make sure you double check and recheck everything you pulled apart to see if they're in working order that way you can get everything in one shot.hope that helps

Are you sure that you have to remove everything in front of the motor? The other how-tos never mentioned removing componets from in front of the engine.

okay ask the other how-to's how many 350's they've worked on.i wouldn't tell you this to sound complicated or its useless to do it yourself. im trynna help you out amigo.if this is your first time trust me your gonna want to remove them.this is because the alternator bracket and a/c bracket are in the way of the valve covers.if you cant take off the valve covers you cant take off the heads.also the alternator bracket and a/c bracket are both mounted on the heads.if you're really serious about doing this yourself call me 253 238 9217 ill explain to you whatever you need explaining on just ask for ernest.
