Head Replacment

i have a 2000 350 mag mpi
i am replacing the heads should i replace all the head bolts they are all in good shape none broken or bent and should i use anything on the bolts sealer or lock tite also should i use any gasket sealer on gasket for intake manifold and head gaskets

i would reuse the head bolts if nothing is wrong with them use thread sealer on them do not use lock tight it will effect the torque if you re torque them after the first run DO NOT USE ANY SEALER OR GASKET MAKER ON THE HEAD GASKETS just make sure the mating surface's are clean and straight use a little gasket maker where the head intake gasket meets the block gasket and be sure to use the proper torque sequence 30lbs 60lbs 90lbs i believe in the proper bolt patern pretty much start in the middle go in a circle and work your way out

IMO the head bolts can be reused, did this many times. If they have been removed and reinstalled a couple times then yes replace them.

I use ARP thread sealant on the head bolts, which is basically anti seize and grease. Do not use locktite. Make sure to use a wire brush to clean the threads in the block where the bolts will go. Make sure there clean

Don't use gasket sealer on the head gasket and only use a small dab of sealer in the corners of the intake where the two gaskets come together

sorry the torque specs are 25-45-65lbs Helical Sequence

Ok, I'll be the troublemaker. :lol:
For $80, I just use new ARP ones. 1) Because of natural bolt stretch. 2) because I'm too lazy to wire brush off the sealant and corrosion. 3) New bolts provide a more accurate torque reading in general.

YMMV
