Invader or Liquifire Heads?

Post by liquifire1 »

Hello,

I was hoping someone could answer this for me?

I have a 2 sets of heads that look similar one set is stamped A-1 the other is stamped A-2

Are the A-1 stamped heads invader heads? and the A-2 stamped Heads Liquifire Heads?

If this is not the case what are the identifying traits of each head

Thanks
Jon

Hello! Combustion chamber on invader heads will be a deep bowl. Deere heads have a smoother chamber with no real bowl. Don't know about stamping but I think my Deere heads are A-2 might be wrong tho.

1A would be the early version of the Kawasaki heads. Deere heads are 2C
