i was checking this rebuilt short block on ebay. seems to be legit, the company looks reputable and the price sounds good. they claim to have replaced the pistons, main rod bearings, even a reground crank. anybody ever order a short block from them? i just bought a rebuilt cylinder head and its to factory specs, now my other question is if i order this short block theoreticly the headgasket should just go on and drop the head then retorque..right? is there any neccasarry procedures you have to do with new heads and new blocks before putting on the headgasket?
