Just means I have to find clam shells if that's correct.

100% sure. 20+ years with GM dealers starting in 79 and I confirmed it last night in my GM 73-78 parts catalog. As long as you are comparing C10 to C10. C20's and C30's use a different number which are also the same for SB and BB. K series use another number but since the 454 was not offered in a K10 there is no comparison.
