so im looking in to purchasing a head from a guy here locally he says its from a 96 will it work for my 95? he says it's only got a few thoudsand miles since it was rebuilt what should i look for when i go check it out?? is there any way of knowing if its already been machined too low if it will allow for another machining? can i check it with some dialcalipers??? and if so what are the specs? thanks for the help fellas
