Hey Iced,
My 85 Blazer had a bad head gasket as well, but it was a 305. I figured it would be cheaper to buy a used donor motor on CL and swap it in, which I did. I was able to get a long block crate 350 with 20k on it for $250.
Swapped everything over from the 305 and it runs great.
A used motor with lower miles may be a better route too if you have high miles on that 350.
But, I also have access to a cherry picker, power tools and such.
I was quoted about $300-400 for the head gasket to be replaced.
Hope this helps a little. Good luck.

It'll take the better part of a day to get it torn down and put back together, sometimes longer(I would know
). It's not too hard as long as you have a torque wrench for the head and intake bolts. I know FelPro upper engine gasket set will run about $50, you might be able to get just the head and intake gaskets separate for less.brooks294x4

not a bad job as long as your a semi compitent mechanic, like said before, a good full days job, also a good way to see what shape your internals are in. if you plan on keeping the motor, i would tackle the labor yourself and spend some of the money on parts, like valve stem seals while the heads are off and maybe a valvejob, will make a world of difference having good heads on your motor. just my $.02.
PS. i PM'ed ya about the tailgate, let me know if ur still interested and well work somethin out

If you're a "might as well while I'm here" kinda guy like me, it might be cheaper to farm out the job. I had a bad head gasket on my 86 F-250 and it only cost me $2000 and a rebuilt 460 when all was said and done!

I second that! When the heads and intake are off, the lifters are just right there, you could pull a couple, and make sure your cam is okay, you can also see what kinda shape the cylinders are in, see if you have a crazy lip or not.
As far as price, if they are iron heads, should be under $100, your just buying gaskets.
But, I would reccomend taking the heads to a machine shop, and having them check the valve seats, guides, and seals.
