Can a 400BBM w/cheap aluminum heads compete/dominate against the street LS?

John, just keep in mind this.....Remember those cheap heads will cost in the long run to make them right. Cleaning the ports and entire heads up from nasty casting and any port work you may want done. Making sure there are good springs and hardware installed. "Cheap" heads are well known for having parts that are less than standard for HP applications, so that's possibly more money outlay. Also the valve guides and seats and valve job in general needs going over.....just everything you'd normally do with any aftermarket head. It'snot just a "bolt on and go" kinda deal. The last thing you want is buying "cheap heads" and them ruining your entire build.

Look at what you've said. You want a Jim Laroy type build.....and cheap heads. Cheap up front, but possibly very expensive out back. Think about that.

Just some friendly advice from an old friend.
