ok heres the deal. i have an 89 auto lb-9 that has been bored .030. My tpi heads has a very bad valve seal leak and instead of rebuilding them i can get a pair of centerbolt iron l98 heads and an lt-1 cam for dirt cheap. i know that the l98 heads are 64cc and they gonna lower my cr down. im wondering by milling the heads, will i keep the c/r around the same. is it worth getting the l98 heads or should i keep my lb9 heads and rebuild them since my lb9 heads has been milled when i had my 305 rebuild.

 

ttt. i really need some input on this.

 

you can replace a valve seal in a couple of hours for a few dollars compared to several days and a lot of dollars for a head swap. if the only reson behind this is to replace valves seals you're way ahead to change seals and not heads.
