New AFR 235 cc heads I was just reading " Last hurrah " by Mr. Mamo and he mentioned a 235 cc head in the making. Has anyone heard of or about the new goods, and when they will be for sale to the public.

I am working on the design as we speak....in the home stretch but that doesnt mean they will be in Production anytime soon. I will say that the new combo I am building for myself personally will be running these heads and I certainly plan on having it in my car by the time the nice weather hits.
In the past we have disappointed some of you folks trying our best to estimate realistic release dates so I wasnt going to make a fuss about them till they are very close to a viable product we can take an order on. I dont want to hear people wining if we run into some issues that delay the release....therefore I wont promise anything.
Read between the lines though....there launch date is not 6-12 months away....hopefully just a fraction of that.
If you can wait abit they will be worth every minute you did based on the flow curve of my prototype....the last trick is to get a production piece of the CNC machine to do the same but Im confident given the time that we can nail it.
More to be posted soon....I will keep you guys in the loop

A six bolt head isnt necessary with a .750 thick head deck till well over 1000 RWHP....even then with the right tune-up its still an option. Im not saying it wouldnt be a nice luxury, but 99.5% of the people reading this wouldnt ever have the need for it.
The 235 will be a bolt on piece that accepts factory hardware (rocker gear etc.) and will not need a valve cover rail spacer either. It will bolt on as easily as a 205 or a 225 head we offer.
It will come with larger pushrod tubes drilled from the factory to clear a .375 pushrod as well as a 1.550 spring pad to accept a solid roller spring. Unlike the 205's and 225's, AFR will offer a solid roller package direct from the factory should you choose to order it that way. Its going to be very "solid roller friendly" which makes sense when you step into a head of this caliber. For the guys that want to stick with hyd. roller cams we will still offer our upgrade hydraulic 8019 spring and titanium retainer as standard equipment. There will be an upcharge for the mechanical roller set-up that will be good for up to .700 gross lift (perfect for a head that looks to peak around .600-.650 lift).
I will share more specifics about this product as it gets a little closer....
Thanks,
Tony

what size chamber will this head have. and how wil it flow boosted wise compared to your 225. i want your 225 until i head of this. so on a 18psi motor is it worth me waiting for this or just doing your 225.

The only issue may be chamber volume for the boosted guys....the initial release will probably be around 64 cc'c but we plan on producing a 74 cc piece also to be released later. I would hate to have you waiting for months in the event it drags on. You could always get the 225's and sell them down the road after the 235's are in production if you dont want to wait.

You told me that I could have a set by the end of this month. I'm holding you to it.
But seriously, back to the 6 bolt stuff. Can you drill the heads for the extra top bolt? Would this hurt the strength of the head somehow? Would it help to keep the heads from lifting without adding the material required to use the one on the outside or would it just make the head lifting on the bottom more likely?

How hard would be to add the 6 bolt to the casting?Trust me not many will be buying 4 bolt heads a year from now.

The .5% is out of luck....LOL
It would mean all new tooling and its not going to happen. The reality still remains that alot of folks are making close to or just above 1000 HP and not having major issues with the four bolt design due mainly to the integrity of our current head deck at .750 of an inch.
I dont argue a six bolt design wouldnt be nice for the small percentage that need it, but our cathedral Gen III stuff will probably always remain in a four bolt configuration.
