Hello
I was cleaning out a garage and found a pair of heads that is to a olds 455 but I dont know what year.
maybe someone knows? it had a vin number on the side of them saying CFD, and then 413 - 191 - 202
can anyone help me? sorry about the spelling im swedish...

thanks

There should be a six digit casting number above the two center exhaust ports. If it is 413 191, these would be the K heads. K heads were used on marine motors and as a parts counter replacement for most of the performance big block heads. K heads are good for performance. You will likely hear from someone that K heads were the replacement for W-30 heads. In fact, by the early 1980s they were listed in the parts book as the replacement for just about every older big block application, so don't read too much into that.
