hey guys.....i need some opinions....me and my friend are building an 86 camaro hes doing the motor and iam doing the body work....he says that hes gonna put 305 heads on the 350 that we are putting in (not an ls1) i was wondering if it would be better to port the 305 heads and put them on or keep the 350 heads and port them....please give me details and ideas...THANKS

 

I wouldn"t use the 305 heads,as the have smaller ports and valves!Also which 350 heads do you have?They my not be that good,If they need to be rebuilt(guide work,valves,springs,screw-in studs,milling,)you might be better with aftermarket heads,such as Trickflow or Canfeild from competition products.com.These heads are about $900.00 and will make good HP.Remember your heads will make or break your engine in the power dept.I needed more info on your motor build-up and budget!

 

Vortec heads are 500 complete and good to 350- 400hp with a healthy cam. Ditch the 305 heads there junk.

 

The 305 heads are junk. Put the 350 heads on and you'll be way better off.
