Help Picking heads for 224/228 Cam and Full Exhaust
Hey Gang long time no post,
Due to a broken spring on #3 intake, my plans to upgrade my heads have been accelerated and I need to pick up a set quick.
When I initially envisioned the build for this car, I was doing my best to copy an old AFR Mamo Combo from over 10 years ago.
Obviously the head tech has changed and the new heads are improved and or seemingly much different.
Trying to get back into the tech details of this, but i could use some help with the new revisions of the heads on the market.
I'm thinking Trick Flow or AFR for the head replacement.
I'd like to stick with the reputation and quality of the AFR's but their line no longer includes the 205's, now 210's.
I see Trick Flow has a set of 205's I'm wondering might be a close match to these old AFR models.
I know there's more to the head power/efficiency than that single spec, so I'm hoping someone could give some opinions.
Cam Card
I'm willing to mill the heads as long as P2V isn't an issue (with 112 lsa, idk if it might be?)
Goals for this build are an all around torquey street car, not intended for much strip use. Mods are in sig and I think i have intake and exhaust covered for these goals.
I intend to get rid of the auto trans at some point, but until I can afford a conversion to manual I'm stuck with it.
I'd love if anyone could chime in with opinions on the heads I've considered or any others that might have filled the AFR 205 gap since 2005.
I'd look into the TFS 220cc heads from Brian Tooley. He can hand work them and make them just as potent as the TFS 215cc CNC'd heads. With powdered metal guides, which he does, and you can run stock rockers.
You can't beat the Trick Flow as cast 220cc head for the price and you are not leaving much if anything on the table. At the time I bought mine TEA added the powdered metal guides for only a $100 more.
If Tony Mamo inspired your quest, you might just ask him what parts he would use to replicate it today. My guess is a Comp LSL lobed cam with similar valve events, MMS 220's and a Mamofied Fast 92 or 102 (with ALLL of the prerequisite supporting mods) would gain power upstairs while losing nothing on the low-end.
Tony's new venture permits him a great deal of flexibility with parts, including TFS and LS3 heads. No doubt he could set you up very nicely!
TFS 205's 58cc chambers and 13.5 degree will bump comp to 11.5 - 11.8 dependent on the Head Gasket choice.
220's will not shine with that camshaft, and will require cutting for comp bump.
The TFS 220cc heads by Tooley will be better than the TFS 205cc heads. The 220's can be milled for a 12:1 compression, which will make killer under the curve power and the 220cc heads will make more power up to.

Maybe Brian Tooley will comment on this. He stated to me that his worked 220cc heads are just as good, if not better than the 215cc CNC'd heads.
The OP wants a torque street build and plans to stay with a 3.893 bore the 205's are perfecto.
Too many people get caught up in larger is better, which is not so. On a stock bore the 2.000 intake valve is perfect and the fact of 58cc chambers from the box requires place, torque, and play.
If he was planning a max effort larger duration camshaft I would say 220's and dial in the VE for max effort. For a torque monster street car mimic my build.......it's powerful and torquey everywhere. It peaks sooner but I'm not spinning 6700 either.
No argument that the 205cc heads will work extremely well. There is a build on here where a guy is running them with a larger cam, and the 205cc heads really helped the larger cam retain a ton of low end torque.

That guy is me and to validate my decision, I've purchased a set of 220's to compare against.
Tony Mamo has a new version of the AFR 205, it's his own design and is designed to get 300cfm on a 3.78" bore... I am sure they would be perfect for what you are trying to accomplish.
I did end up contacting Tony directly and am going with his recommendation.
Details to come soon.
Thanks everyone.
