Why can't you take all the components out of a B series head and put them in a 89 older teg head??? I want to really bad.

 

Because you don't have a B series block and can't use them.

 

that's why you have to use the teg head. Okay tell me this how come I can put an CRX Si Cam into a CRX DX?But not all the guts from a b series head into a
d series head?

 

many reasons for starters thry are 2 totally diffrent blocks / heads, ewith your cam swap you were swapping a cam from a d series into another d seires. it's like how people can swap itr cams intot here b16a there bother daul over head cam.
