head gasket question

[doorvip]

I just bought a reman 302 long block, it has never been run and I want to change the heads. can I used the head gaskets that are on it or should I change them.

 

[Grn92LX]

if you remove the heads the gasket needs to be changed. Use a fel pro 9333pt-1 gasket.

Agreed, the gasket has already been compressed. Once compressed you don't really need to re-use them, you (could) re-use it but you will not get as good of a seal as a new gasket will give.

No point in reusing them. Just asking for trouble. Go with the 9333pt1 like grn92lx suggested, I believe they are 15 bucks each and your local parts store should have them in stock.

I will thrid those gaskets. I've running them on my 331 with 8lbs boost with head bolts - no problems. I know one place that uses them on 9 sec turbo cars so they will hold up.

do you guys use sealent on your bottom bolts?

 

[mob]

Yes, use rtv or thread sealer on the bottom bolts. Anti-seize on the bottom of the bolt heads and on the threads of the top bolts.

X7 on getting new gaskets. Remember your going to have to follow the torque sequence when tightening the heads down and you'll have different torque values for the bolts that you use sealant on versus the ones you use oil or assembly lube on.

dont use thread seal on head bolts... use 10 30 non syn motor oil on the tread of every bolt

if your cutting corners buying gaskets, id leave the motor alone

new gaskets for sure, head studs if you got a couple extra bucks.

Seal the bolts unless you like having a milkshake in your oil pan.

I've never had a problem with just using motor oil on the bolts and I've had the heads off a bunch of times, never got a milkshake in the pan from not using sealer
