Stock heads on 87 305 tpi?
Just curious as to what heads are stock on an 87 iroc tpi with 305 5 speed setup. I ask because i believe the 081 casting is the stock setup but I found 187 casting heads on the car which are the swirlport tbi heads.

I did do a search but I didn't come up with any definitive answers as to what came stock. it's a stock motor otherwise but I am pretty sure the 187 heads are not the stock heads. Just looking for a definitive answer on what came stock.

So for ***** and giggles I put "081 Heads" in a Google Search...
Took 2.5 seconds to find this....

I had 193 SwirlPort's on a TPI 350 "stock replacement heads" I was told for an engine that was blown...
The engine also came with a tiny 305 Cam... 179/194 Duration
with that combo it made 300 ft/lbs at 3100 RPM
I think that the swirl ports are great for Torque especially with our TPI's (which were designed to make Tq anyway...)
Now use that might mouse and Search...
