According to the guy at the Machine shop it is suppose be more reliable and have a higher compression vs factory. I should have my block back this week

JE pistons are made for iron sleeves you can't use them in alusil block (or you have to coat the stock pistons with ferrostane or similar material), but there's no need to sleeve the block - you can just bore it out from 92 to 93 mm and re-use the old pistins with new piston rings - it's much much cheaper, than putting the sleeves and new pistons.
1 mm bigger bore costs here in Europe about 600-700 Euro for 8 cylinders, a used 4.4 block is about 200-300 Euro max. a set of new piston rings is something like 150 Euros. Thats it!
