Gotcha, thanks guys for the replies. If I'm going to buy heads, im just going straight into it w with aluminum saving weight and a bit more power out of them than cast. Any of you guys run the edelbrock e-205 heads? They look pretty nice and price isn't too bad even assembled

Historically, Edelbrock heads have junk valvetrain. It seems even more common in the E series heads.

So, I'd expect to at least buy new springs and change the studs to good 7/16 versions. Preferably, I'd also change the retainers and locks over to 10°.

That's 600.00 to 800.00 dollars.

Thats cheaper than what I figured. I was over $1000, not counting the likelihood of needing new guides. That is, assuming that you had to pay someone to do all the work.

That's what my cylinderhead machinist charges for simple setups on iron heads.

Fordota has a set of iron heads done up by this shop.

Ugly?  Easy now -- that's my baby and it's got lots of unique character!  When I drop that built 445" stroker in it you won't have any time to "pull over to let me pass" because I'll have already blown past you when you figure out what the hell was that loud noise behind you . . .

I was also figuring at least $400 in decent parts, more if high quality stuff is wanted. Valves, springs, retainers, locks, guide plates, and studs.

None of the least expensive heads are going to come with full race quality valvetrain components...  then again, neither did anything from Ford.

It all depends on what you are going to put it on.  If you're building a 6k rpm street engine with a hydraulic roller cam...  what Edelbrock sets you up with will work just fine.  If you're building a 7.5k rpm race engine with a solid roller, you'll need to step things up to more race quality parts. 

If you're looking for heads that standard headers will bolt to, the Trick Flow Twisted Wedge units are good, as are the mentioned Edelbrocks.  AFR also makes a top quality head with good parts.  They're just not cheap.  Depending on the head, you may have to do some grinding on the header port openings where they bolt to the heads, as a lot of the AFR exhaust ports are pretty wide/tall. 

Just don't be tempted by Chinese junk.  Any Edelbrock head is way ahead of those, quality wise, when it comes to parts and machining.

Good Luck!

No, new pistons are needed for compression changes, power levels, or a much different valve angle like the Twisted Wedge heads. Mild level pistons are still reasonable.

There is no way in hell that I'd throw that much money into a set of factory Windsor heads.

This x10000000000

 Welcome  Spt at PC

This saying took me a long time to believe or do...lol

BUY ONCE.... CRY ONCE

My first real heads were twisted wedges...years ago at $1050 but even now at 1300’ish new there a great deal especially for a stock piston bottom end

my way is 375.00-400.00 around here.

1.94 /1.60 SWIRL POLISHED NECKED DOWN STAINLESS SI VALVES @9.00 EACH
POCKET PORT BOWLS
HARD EXH. VALVE SEATS
MILL EM FLAT
SCREW IN STUDS
GASKET MATCH INT-EXH PORTS
VITON SEALS
SPRINGS TO MATCH CAM
GUIDE PLATES

I'm sorry, but your math doesn't add up to me.

You are saying that you can buy new valves, seals, springs, retainers, locks, studs, and guide plates.

Then pay someone to cut the seats for larger valves, install hardened exhaust seats, valve job, mill, machine for studs/guide plates, machine for double springs (you should!), and assembly?

For $400? I really need your supplier and machinist's numbers.

I didn't count the bowl blend or port matching, assuming that you'll do that yourself. Or the extreme likelihood that those 50 year old heads also need new guides.
