305ho heads on a 327/350?

Trying to figure out this motor I got.Under the valve cover was 14022601(305ho)back of the block 3970010(1968 327,1969-79 350).Why would this head be on a 327/350?What are the benefits,if any?How can I tell if its a 327 or 350?Any info is appreciated-Marcus

 

I ran those heads on my 327 for years. Better flow and slightly higher compression.

 

Good set up ,If compression on your motor is lets say 8.5 to one the heads will raise it to 9. to one ,,,,At least thats what I was taught .

 

Smaller valve combo and I think a 58cc chamber. The HO heads are what gives the 305 better bottom end power and better mpg usually over the standard crappy 305 head. Those heads on a 350 or 327 would bump compression and also add to the torque

 

Im still trying to find exactly what this motor is out of but have not found a definitive answer Block vin/suffix codes are 112151281 K11 18 CKB According to Chevymania CKB=72 350 chevelle,73 350 nova,73 350 chevelle,73 350 camaro,74 350 nova,74 350 camaro,77 350 impala,88 305 impala . Head #14022601=267,305ho 79-86 Block#3970010=1968 327 1969-79 302/350 Any help with maybe narrowing this down?

 

I think that's exactly right...that's the way I understand it too.

 

Don't worry.. Be happy! Sounds like a cool combo to me! How does it run???

 

i got a set of 416 305h/o heads on my 400+ horse 327. Lots of port work done and good valves.

 

I didnt want to beat on it(yet)Still need to do a few things to the car.Pulled the valve covers today and I cant believe how clean the heads are,no dirt,gunk,,just really clean.In a few weeks I will chime back in and let ya know how it runs....It sounds really good

 

Mmmm... I wonder how it went..
