The gen II LT1 has reverse flow heads, so without some major modifications, it wont work. And LS1s are a completly differnt animal all together and will not work.

You can probably get an answer for that question on the internet. If not go to your friendly parts counter at the GM dealer and he can probably help you. There are many online groups which answer that sort of question too. Like a hot rod group.

Can i put a set of stock 1997 lt1 heads on my stock 1987 350


no. the 97 heads are designed to run port fuel injection with a dry intake manifold, where as the 87 fits the old throttle body injection set up with wet manifold runners.
