i looked on LC and it said that 80-84 tall and 85-95 short the measurement they posted tall is 11.280, so i figured that is would be about 11 and a 1/4 with a tape. short is 11.090 i figured 11 and a 1/16 on a measuring tape. i measured from the oil pan rail to the top of the deck and it was about 11 and a 1/4 so i figured that i have a tall deck witch is what you want for the 20r head if I'm wrong i don't want to buy all the stuff and end up having the wrong block so please tell me if some one knows or can measure theirs that has a tall block and post it thank you.
