Re: LS7 HEAD 454 3994028
I've owned these #026 cylinder heads before and consider them to be the long-lost, mysterious ZLX heads. They were the first cast iron, open chamber, rectangular port cylinder head and were similar in many aspects (not all) to the aluminum L88/ZL1 heads. Definitely over-the-counter only because no production car would've had these.
