Hello all. I am in need of some desperate answers. I have a 1995 chevy S-10 4x4 blazer with a bad engine. I have purchased a new engine with low low miles from a 2000 S-10 2wd with the same vin code as my 95. i was told that i could just switch the upper and lower intakes but then found out that the bolt holes do not line up. My question is will the cylinder heads from my 1995 engine bolt onto the 2000 block so that i can swap my intakes and plenum to the 95 style? Any respones would help greatly!!! If this will not work is anyone looking for a complete engine from a 2000 s series truck with only 45k on it. I really hope that the heads are interchangable but do not want to dissasemble the engine i bought if the old heads will not bolt on. So to sum this up will the heads from a 1995 4.3 vortec engine fit on a 2000 vortec engine???????????????

Yes you can put the 95 heads on the 2000 block.
Use a new set of head bolts. Buy the Fel-Pro head bolt set for the 2000 year and use the torque specs for the 2000 year. This will be torque + degree tightening spec. Fel-Pro sells a low-cost torque angle indicator wheel if you don't have one yet.
I would take the 95 heads to a machine shop to check for straightness. If it has high miles it would be a good idea to have the heads rebuild (grind valves, check/replace valve guides,new valve stem seals, check springs) all this would cost about $300-$350 and would be much easier to doo now than to take em out later.

I would have to agree. Get the heads rebuilt and machined. It will save you headaches, and more cost in the long run. Also, definately get new headbolts. The old ones will have stretched from the torquing, and you will get leaks if you don't replace them. :2cents:
Good luck, and let us all know how it goes.:iceslolan
