Power Gains???
On a stock 302 block if I were to put on 351w heads (ported with a valve job), 1.6 roller rockers, Trickflow stage one cam, cobra intake and long tubes what kind of power do you think that I would gain and maybe even put to the ground. I also am installing a NOS 5115 kit.

what year windsor heads are they? cause if there not from 1974 or earlier, there almost worthless power wise (dont quote me on that year exactly) From my understanding the best windsor heads to have are the DOOE heads, and even then I believe a set of iron gt-40 heads outflow those windsor's.

even thought they are free you are going to spend 100 on gaskets and are they coming off a running motor? if not you are gonna want to get em resurfaced and proly a valve job the seals may be worn out.

if they arent rebuilt and ready to go, your wasting your time.
instead look for some gt-40p heads that you can work over. you will be better off in the long run
