IIRC,in order to use aftermarket pistons,you need to get rods that are a hair longer.The distributor is a little longer.You need a spacer to install a normal big block intake.All these parts are easy to find,but as mentioned earlier,it ads to the price of a build up.Tall decks are mostly used for the big stroker kits.If you want one,go for it.If you don't,drop it off at my shop and I'll give it a home.
