I got a set of 113s and Im trying to sell my rebuilt vortecs but I guess$400 is to much so I havent gotten a lot of hits on them..anyway if I cant sell them would I be able to switch the valves,seals,retainers and springs over to the 113s.both are stock but the 113s have 90k and the vortecs have less than 4k.thank ya much

 

Not sure why you would do that. Vortecs should outrun stock 113.

Stock Vortec springs are performance junk. Were they replaced during the "rebuild"?

The valves would interchange, though.

 

The motor is only a 305 and I figure even when I build my 355 its not going over 350-400 horse so with some work those 113s will flow plenty..plus the vortec intake are harder to find used and more expensive, plus the 113s already have screw in studs and guide plates. The vortecs were already rebuilt when I bought them. Im assuming they were rebuilt with stock parts..any way for me to check the lift on the springs?
