I have a 1990 beretta gtz sitting in my driveway with a blown head gasket. I was thinking instead of replacing the gasket only to have it let go again in the future, I was thinking of swapping in either an ls4. or an l67. I know I can get the l67 in there but not quite sure about the ls4. I guess I am looking for some advice, opinions etc. And yeah I know. "IT's A BERETTA" Just looking to do something different.
