I have to pull my heads to replace a lifter and was wondering if there is any other heads that I might gain from while I have the 205s pulled?

Let me know what you think. My Sig has my current mods in it.

Thanks for your help.

The AFR 210's they are beast, just did a head/cam swap on mine with them

There are many heads out there that will benefit your setup over the 20s, that's for sure.

Only thing is do you want to spend the money on them?

I vote for the new PRC 227 casting, or maybe the AFR 230 V2.

Heck, even AFR/TFS 225s/215s will probably make more power. As will a good set of ported L92s.

what are your HP goals?IMO,unless your looking to radically increase power,i would just leave them alone.

DO you think I'll gain HP from the 205s if I go to the 230v2? I know i'll end up spending more money, but I think that my 205s are still worth some bucks... So the difference my only be a little cost...

I do plan on hunting down more HP, but I'm not putting another cam in it anytime soon. I wish I did larger, but its too much work to swap the cam unless I'm in there for something else. I may blow it next year tho. Is the larger CC head going to matter if I do that? I just have so much more to beef up before adding a blower. (Rearend, Clutch, ect.)

The car is fast enough now, but I just added 20" Z06 sized tires in my widebody conversion. I just want to make up for lost ponies. I think those tire weight 50lbs more per corner. (360 Mesh 8s)

Tfs of you ask me!

how much horsepower are you looking to gain....I think you have a pretty good street set up as it sits since your cam, in my opinion, is a bit on the small side. If you're willing to put the money into getting new heads, I would look into getting a new cam to actually make a truly noticeable power gain.

More then likely you are going to gain some power, the 205s are relatively small for a 364.

Yeah, I know I went a little small on the cam. I was a little worried it would be to loby. I underestimated how much I love it. Plus didn't realize how much could be tuned out of it.

I don't want to do a cam in the short term, it was a lot of work for me to tear up that front end. I wish I would have put a 2 piece chain cover in. That would make it a little easier.

I'd like to make 500rwhp some day NA. I know the cam has to go for that to happen.

Does it make a difference if I blow it later? Like is the size of the heads going to matter more or less if I do?

redtan

The more air comes into the engine the more it matters, so if you plan on supercharging it then yes it's gonna make a difference.

one option to look at is to send the heads back to AFR to get them "Mamofied",and open the chambers up to the 4" bore.Tony could tell you for sure about the pros or cons of doing that,as well if it would be cost effective compared to just buying another set of heads.

Not a bad plan, but I think i can still get 1700-2000 dollars out of my 205s. I was thinking about the 230v2, but I cant find them for sale anywhere. I was going to call PRC about theirs..

be patient and save some more money...put a blower on it the way it sits

I think the PRC 227 head would be a great option especially with a camshaft upgrade at the same time. Tell us about your current setup, what cc is your chambers currently? 59cc??

If you want more power, I would go with a bigger cam. I think swapping heads would be a huge waste of money for you. There are people that made 500 or close to it with those heads, plus the few hp you gain you will be trading for midrange and torque. There have been people using them on their 383's. The mid flow numbers are whats important and those heads are as good as any.

At the end of the day, if you goal is to get to 500 rwhp N/A, you'll need to go with different heads and a bigger cam. If now isn't the time for you to tackle that then I'd just bolt the AFR's back and go with your current setup until the time comes to go bigger.

Just bolt them back on. I have AFR 205s sitting on my ERL 427 LS2. ... it's not so bad.

^^^ x2 ... only because I am running TFS CNC 215's and making good power. They flow very well.

I have actually been seriously thinking about this ^^^, but right now I am concentrating on my suspension to get it to hook.
