I bought a 1986 iroc camaro that came with a 305 tpi engine. The block is still 305 but they replaced the heads with 1969 corvette heads and a 4bll carb. I want to put the tpi set up back in the car I have a set of 1972 350 heads. can i use the 350 heads on the 305 along with the tpi set up?  

if the itake manifold bolt holes line up and the runners line up then yes you can use 350 heads on a 305.  the only ting you have to worry aboiut is if the intake lines up.  

i thinki was smoking crack the day i answered this.lol.  350 valves will shroud or crash in a 305 cylinder bore.  i hope this guy didnt take my word for it.
