Thank you L4staero! Of the Apache style heads that are made with the higher grade aluminum, these BG heads appear to be a great deal. I figure, with the core charge included, that a pair would cost about $1972.00. The Edelbrock 3G Hemi Performer heads are about $2600.00 for the pair and the cheapest I found the Thitek heads were $2449.00 per head (A2Speed). If my numbers are way off please chime in. Thanks again!
