AFR Milling for 228R
Looking at the AFR 205 heads for a TSP 228r. Read about so many combination's what would work for me? The car is an 02 Z06 it isn't a DD mostly fair weather, I autox about 3 times a yr. Im looking for more low end grunt and some more fun on the street. Suggestions on keeping it the 66cc or mill lower and head gasket.
Thanks

Here is my experience, hopefully you can get some guidance from it. My heads had the chambers reworked by Tony Mamo. He was shooting for a 62cc final chamber size. His work removes about 2cc of material from the chamber so that the final mill is equivalent to a 60cc mill for the standard head. I am running the AFR 6016 cam, 224/228 on a 114 LSA. My intake PTV was slightly under minimums and my exhaust was fine. I would think the 228 would be OK with a 62cc chamber (from a mill standpoint, that is 0.012" less material removed then mine) but as mill more the PTV could become an issue. I would speak directly with Tony, he has done enough he can likely tell you where it will come out. I would also get an adjustable timing set like the Cloyes Hex-Adjust so you can degree the cam. With your cam selection, you are not going to believe the response of the motor when it is done.

Thanks for the info. I've tried pm'ing Tony and emailing AFR unfortunately haven't got any responses why I went to the Forum. Don't have the time during their working hours to call which would be best option.

I have this package for $2758 to your door or $2858 with the heads milled. We will also grind you a custom cam for the same money.
Having Tony work the heads will cost more money and to be honest with your goals you don't need it, the 205 will perform great out of the box. You can call me anytime, due to our engine customers around the world I make myself available 24x 6 1/2.

I only had a symetrical 221 575 112 in my 98 and the difference was very noticable.
I actually have a higher lift 228 cam on the way for my Z06
Edit- OH, I see you may have meant the difference between a 224 and a 230. Yea, the difference between the two isnt big numbers, but it does shift the usable power up or down a bit

^^ Very true, you might make more peak but at the cost of low and mid.. what rpm do you want you power served at is the question. then you have to look at the added stress of the higher rpm peaking cam and weigh out the options while looking at whats more dependable given the current short-block.

I think everyone misread me. I meant if one installed a 224 cam , then a 224/228 cam a 224/230 cam with similar lobe sep. You couldnt tell from anyone of those grinds. Dyno would be very close. Now any of those cams from a STOCK LS1 or STOCK LS6 cam is a huge difference in power and SOTP.
