Okay thanks for the info. i found two on ebay from separate sellers, both say they are reman. Do you guys think remans would work well? also do you think my block surface could be warped? and if so is there anything that i could to myself to smooth them out? And another question is that it would cost me about $775 to get just those heads not including gaskets and whatnot, do yall think its worth it? i got the truck from a buddy and i have about $500 in it. New lifters gaskets and such.
You need to make a judgement call. You know the engine better than anyone if you have been driving it awhile.
How noisy is it?
How much oil does it use?
Have you ever drained and flushed the coolant? If you did, was it rusty?
How many oil leaks do you have?
Answers to the questions above can help determine how much you need to do. In my case, when I got my engine the coolant system was so clogged with rust, it would not even come out of the radiator. I kept flushing it and flushing it. When I finally got it cleaned up, one of the freeze plugs started leaking. Barely got a rubber style plug in there, and then another started leaking.
I then had one of the rubber plugs pop out on the road. It was pretty obvious when it happened and I pulled over to the side and cut it off. It did not seem like it really overheated, it did not use a drop of oil, and had lots of power. So I thought it was worth spending some time and money on it.
I pulled the engine, glad I did, there is a freeze plug between the engine and the transmission that you can't see, and it was seeping. I was going to reuse the heads, and while I was cleaning them up with brake cleaner, everything turned that brown color except this strange black line. You could see it on top of the head where the valve cover would go. A long black line. I cleaned it again and again, and it always came back. So I figured it must have been a crack.
So I went on ebay and got the updated heads. They want your heads back, so I assume they take all the used valves and pieces, and installed them in this new casting, and then sell them as updated heads. They have been on there over 10 years with no problems.
I took a peek at the bearings, they looked great. Oil pump looked good too. I just put it back together with the new heads and a full gasket set. The full gasket set is cheaper than buying them individually. Put a new timing chain set in it. It's been a good engine.
