yes
Yes.
327 heads do not have the mounting holes like a 350. Alt, and a/c brackets although if you are not using serpetine pully's they have no problem going on a 350 I have a set on my 350 and it runs absolutely beautifully
bore it out to 301 cu.in. port and polish heads ( look for a good set of dbl. hump heads ,mostly where on 327-375hp) good cam ,helps a lot GM made a cam that was for hdy lifters an was good for 350 hp was used in 327 corvette's 62 thru 66
Yes, need an electric fuel pump, o2 sensor and tpi computer and wiring harness This combination could increase the compression ratio. Watch out for detonation. Premium fuel may be required.
Set the motor to TDC, pull the #1 spark plug, put a small wooden dowl rod in the cylinder, rotate the engine and measure the stroke. 3.25" = 327, 3.48" = 350
yes they will i just put a set of double hump heads on my buddys 94 z 71 and they worked great.
yes there are 8 intake valves and 8 exhaust valves in the set of heads
replace the intake gasket set
how do i set a 327 9 degrees back
I don't know why you would want to spend money on 305 heads, when you could take that money and buy a set of good 350 heads already beefed up and ready to go.
Yes it does work. However you will also need to use the 22 lb injectors for the 350. To get the full benefits from the upgrade you should get a 350 chip burned. The computers are the same but the chips are different. This is all considering if the swap is for a lb9 (305) to a l98 (350).
well i bought a pair of pre assembled dart iron eagle heads for my 383, mine is all performance though with 2.o2 and 1.60 valves and double springs etc. for 350 and mild 383 you should get a set with 1.96 and 1.55 valves and a smaller combustion chamber.
