Will 350 LS1 heads fit on a 305 TBI?

I have a 1989 Chevy Camaro with a 305 TBI engine. I also have a heads off a early 90's corvette LS1 and wanted to know if they would fit on my 89 305 Tbi.

LS1 heads will not fit, LT1 heads will not fit.

You might want to figure out what you ahve, the LS1/LS6 didn't not start production until '97 in the vettes. from 92-96 there could have been an LT1/LT4.

If they are from pre '92, then they are likely L98 Alum heads. If that is the case, they will fit.

LS1 is not a 350.


(I think its like 347 or 346 sumtin like that, and its bore is actually smaller than 350's ar around 3.86 or so.) (Not exactly sure on exact numbers though).


Everything else what Dewy said!
