Hi, I'm looking for a pair of 360 heads for a LA 318 (1974), preferably, 1.88's, ready to bolt on but will consider builders. I am putting together a 318 while I rebuild the original, numbers matching 273 4 bbl in my 66 Barracuda Formula S. Yeah, I know, don't build a 273. As mentioned, numbers matching in my Formula S. Thanks.
If you're using the stock exhaust manifolds, you'd be better off using 273/318 heads and installing larger valves. That way the port sizes will match better for flow and less prone to blow gaskets.
