243 cylinder head ?'s
Just got a pair of 2006 243's off a 5.3 h.o. .My question was are the valves longer like they are for the ls6 or are they standard length. My second question is how much should I resurface the heads to use them on a 4.8/5.3 non h.o. without losing compression and to gain compression say 10:1 or 10:5.1
thanks Chris
