I understand the head gaskets & freeze plugs are different in a marine application. My question is are the block & heads the same as a 4.3l in say a 2000 vortech blazer. I know that the marine engine is carbureted and the blazer would be fuel injected. Thanks for any insight.</p></blockquote><p></p>
