yes you sure can.
Need to know what year the engine is, that you changed the heads on and what it is in.
350 heads will bolt to the 400 block. They will need to be drilled for the "steam ports" in the 400 block.
a 350 is a small block those heads will fit on and Chevy SMALL block not a big block
yes, you can use those heads. the block does have small changes to it but no problm will occur
Yes, but running a 350 cam with 305 heads is not effective,you need to run 350 heads as well. In order to benefit from a 350 cam you need something to flow that extra fuel and air, so using 350 heads along side of the 350 cam will be the cheapest and best choice. HAVE FUN!! A 350 head can physically bolt onto a 305 block. However, 350 heads can have the valves extend into the cylinder and contact the cylinder wall (even with the smaller 305 cam). The 350 cam in the 305 with stock heads will work. You wont want to use 350 heads you will lose compression due to the largers combustion chambers.
lt1 is a 350
Yes their the same block....
yep
how much horse power does a stock chevy 350 have ?
the heads should fit as long as your not trying to put them on a big block
yes just get head gaskets for the 350 not the 327
You must drill the steam holes in the heads to coincide with the ones in the block or it will overheat QUICK!!!
