I agree completely high mileage LS1 combos going for stupid money hence my previous comment, unless I can by a LS1 for the cost of the block and crank I'm passing. 241 heads worth $100 max? LS1 intake worth $100 max? Front and rear covers with new seals $100? Push rods need replacing. Rockers need a trunion upgrade. Fbody pan and accessories are worth more than the heads and intake. L92 or LS3 stuff? again if the price is right. Better heads compared to the LS1, LS2 or LS6 stuff. Run the numbers on new crate short block or complete long block and decide for your self. Don't get me wrong LS versus LT1 I go LS all day long. Unless emissions are a problem the LS engines are the way to go.
