9mm to 7mm bushing

dang lol i figured the would be expensive but not 50 bucks lol

flow and performance wise what is the differance from the 9mm head(non ic) head to the 7mm. i will be running it with a p pump
 
The injector bore is differnt. 9mmvs7mm they will crack tho between the valve and inj bore cuz they are bigger
 
They are also in the Cummins (orignal) upper gasket set
 
so are you saying that you can run 7mm injectors in a 9mm head with these bushings? sorry to hijack.......thanks
 
yeah thats what its saying. it takes the place of the copper washer i believe.
 
how about going the other way, can i get thhe 7mm head machined to acept the bigger 9mm injectors, are there any clearence issues with porting in the head?
 
thats pointless because it makes the head week and it cracks from the inj hole to the valve seat but you can turn the 9mm injector to a 7mm to fit in the hole like I did.......
