Went to sleep, woke up, read this and lmao. Yes yes yes, bootlife, you are 100%correct! Continue to look for 243 heads that were only in a 6.0. -_- some people......
Think of it this way. If they had different bowl sizes, then WTF would they have all the other head casting numbers??????? There'd be no point. 243 cast is a 243 cast no matter what they put it on!!!!
