Chime in on head selection
OK Team here we go, Got some loot from the bonus going into the vette fund.
trying to decide which supplier to deal with
I am running a stock 68 327 small block, and looking to upgrade the top end.
trying to decide between the world, Edlebrock and GM performer heads
looking specifically at the 2.02/1.6 straight plug heads. not looking to race or anything, but good street performance my existing heads are just tired I'm gonna shelf them for later rebiuld.
I am running the stock cam, but will do a cam swap later thinking of the 70 Z28 cam 224/224 w/ .477 .447 & 112 LSA and 1.6 rockers but open to other options
could go either way but leaning toward aluminum.
the car is a daily driver except winter, and see plenty of highway miles (i.e. cruises)
so what are you guys running and price across all three is acceptable, no not interested in the cheapest, but more interested in quality
Thanks team

I ended up going with the World Products Sportsman II. I have never really heard anything negative about them. It was a toss up between the Sportsman II and the Edelbrock RPM. You didn't mention which World or Edelbrock heads that you were looking at, but the Sportsman II is a 200cc runner and the Edelbrock RPM is 170cc runner. The next step up in the Edelbrock line is the Victor Jr., which is 219cc runner, probably too large for you.
You can check out this site to get flow numbers for several heads:

of the three you mentioned I would go with edelbrock performer
RPM there 170 runner is big enough for a mild cammed 327. the
cam specs you put up are not the mechanical Z/28 looks like
they are the 350 HP hydraulic.

They are 2.02/1.6 valves , I took them on trade for a set of AFR heads , they have low miles on them . they look good But I have never run them or dissasembled . I was going to use them on a 355 but never got around to it , that was about 5 years ago

So just remember that you need 64 or less cc heads
