    Default bb head questions

    I am helping a friend do a 454 out of a 90 van. The current heads # 14092360 are 116 CC's and are the peanut style. I have a set of 473328 - 366 truck heads but I cannot find any spec's on the CC's etc. He can get a complete set of # 3993820 heads(200$) that are 113 CC's, which will bring up the CR a bit. My question is does anyone have spec's on the 328's and how do they compare to the 820's. So far I have not been able to find out the CR of this engine, so if anyone knows it would help us. The guy just wants a nice BB in his ElCamino, thanks, Henry.
