Ok guys, I'm doing h/c/i on my car. With all the head options out there I'm a bit unsure as what to get. I don't want to have a four grand in the heads for my ls1, but I'm not afraid to spend a bit. The plan is to pick a head then have a cam spec'd for that setup. I would like the car to make useable power in the mid to higher 400's range. Would TFS 220's do the job? Worth it to have them done over by Tooley? Maybe AFR's?

If you can swing 2500 then get some TFS/AFR 215-225.

If you can only swing 2000, then get the as cast 220s worked over by Brian.

Either way you can go wrong with those types of heads, and with the right cam and compression there's no reason you can put down high 400s.

Would BTR worked 220's be anywhere near the AFR 215's?

Both heads are excellent options and are at most 10 horse apart from one another. One additional choice to research before pulling the trigger is Tony Mamo. He just finished up a 220 head cast by AFR and cnc'd to his specification. He can also hand dress them for a few more cfm. Due to the high velocity design his relatively conservative custom cams produce broad torque bands. It costs nothing to just call him and ask questions.

I did speak with Tony a month or so ago. I unfortunately lost the paper I wrote the prices down on. I can't remember what the price of the as is heads are vs the cleaned up ones by him are. If anyone has those numbers feel free to PM me. I guess its really just coming down to how deep my pockets are? I've just seen too many threads and met too many people who were disappointed with there heads and cam build. Ok so here is where I'm at:

TFS 220 Reworked by Tony
Mamo's AFR 220
TFS 215

More input would be appreciated on people's experiences. I will definitely be running a custom cam based on my head choice. I would like the car to have a nice broad torque curve. I would like good useable power. over 450 that isn't @ 6500 rpm. Doable?
What about PRC?

You're basically splitting hairs by now, as you won't see a huge difference in most of those heads.

Now if you get Tony's own 220s hand worked maybe, but that's running you well over 3g. Honestly, hand worked as cast 220s by a good guy will be the best bang for the buck. Save the $500 over CNC'd heads and get some gears or something else that will make the car overall faster.

I'd either do the 220s work by Brian or the Mamo 220s out of the box. The Mamo 220s will cost a little more. But either of those heads would be excellent.

I wish I had a price on the Mamo heads out of the box. I guess I need to call him again. On the TFS 220, They come from Summit in a 64cc (according to their website). Vengeance has them listed as starting in a 65cc and going down to a 59. If I wen that route, what CC should I be shooting for on a stock cube ls1?

I wouldn't use them out of the box. Tooley installs hollow-stem valves (Ferrea now I believe), his springs, hand finishes the ports, and mills them for you. I want to say that ends up being like $2200. But the port work is great and you end up with a better valvetrain.

Mamo has the 220s for around $2500. You can get them with hollow-stem valves for another ~$200 or so? His hand port work adds quite a bit to the cost.

I thought the base Mamo 220's were 2650.00 assembled? He listed the price in his thread.

You're right. He said they'd be a little more than the AFR 215s. They run about 2400. I just couldn't remember.

The great thing about Tony Mamo combos is that they never have a huge cam but they always make huge power!! Anybody that can get over 460 plus at the rear using a cam less than 230 duration is pimping... it goes to show how effective his heads/intake really can be

MMS220'sout of the box, maybe light valves beyond 6500 RPM
Ported FAST 102, GM 90 or NW 92 MM TB with VMax Velocity Ring
Good for 500+ RWHP and easier to tune vs 102.

I'm thinking the TFS 220 route is the way I'm going to go on this. I've tried to contact Brian via pm here and an email on his website Haven't heard back. Im hoping the phone number on his page will connect me to him. I'd like to clear up a few things with him before I pull the trigger.

Why wouldn't you do a 102 TB? You're costing yourself about 10HP by going with a 90/92 TB on the FAST 102.

I never see the MAST heads mentioned in these threads. Why is that?

Good question

I would answer this but I'll probably get banned LOL.

I still have an e-mail from Brian Tooley from back when I was talking about getting his TFS 220cc heads, worked over by him. He stated that his worked over TFS 220cc heads would be equal to the TFS 215cc fully CNC'd heads. If I were you, I'd go with the TFS 220cc heads, have Brian work them over, and then have him custom spec the cam and valvetrain.

I'm thinking this is where I'm headed. I want the car to make useable power not just a peak dyno number. I already have 1 7/8 longtubes for this project. I'll be running a fast 102 as well.
