Thread: 305 TBI to 350 intake won't bolt.

Tweet

Is there a down side to using the 305 heads on the 350? At least they would bolt up.

I'm running 305 heads on my 350, but both were of the Vortec variety, so they simply bolted on and so did the intake. The only downside is that you lose a little top end breathing, but you also pick up some compression..........maybe a point or so.

Years ago I put 260 heads on a 350, not good my exhast pipe glowed red. Finally sucked a valve.
I think I may just give the 305 heads a quick look over. Maybe lap the valves and put seals in it. I'm worried that the valves may have got bent when the water got in the cylinders.

There is allways a solution to every problem. It usually involves a credit card though.
