Im going to be starting my header install friday and was planning on running the wires in the stock location under the headers. I was also going to get those accel shorty spark plugs and 90 degree boots.

I was wondering to do this do i also need to replace my plug wires, or can i just put the new plugs in with the new boots and use them with the stock wires back to the distributor.

 

If the wires are routed the same, I see no reason you'd need shorter or longer ones....?

 

i used the stock NGK replacement plug and some wires off of a 79 full size chevrolet car.... with 90 degree boots.....

 

depends on the headers. Some fit tighter to the block than others. I ran my wires under my Hedman shorties. Switched to their longtubes and they fit under there, but the drivers side has less room while the pass. side has more.
