Will the AFR 357cc heads work well???
I'm building a 540 tall deck with a whipple quad rotor 2.2L EFI. What do you think of the AFR 357cc CNC heads? Any suggestions for the cam and injector size would also be welcome.

We used the 325 AFR CNC heads on a pair of 540s with a single Whipple. Crane 741 Hyd roller, and 50 lbs. injectors. JE reversed dome pistons. 7 pounds of boost. Idles at 750 rpm and the motors pull hard all the way up to 5600 rpm. Heads are first class. Dont know if they got caught up. It was about 4-6 week wait for a set. Good luck with your quad setup.

We have a set of AFR 357's on the bench ready to go if they are the real deal. I was thinking of a crane 741 with 83Ibs injectors. I plan to run 110 octane and 13Ibs of boost. The goal is 1200HP, or 1000HP on 93 octane.

I think you will be on the short side with 83 lbs injectors if you are going for 1000-1200 HP.

Everthing I've seen on the AFR's has been super positive, will be my next head purchase. 83 lb injectors will cut it by turning up the fule pressure, every 10 psi gives another @7lb rating, so just start with extra 10 psi over where they are rated, probably 43 psi, for that kind of HP.

What is the bore, stroke, rod length on this 540 combo, I will figure the air needed to do so.. .but I think your going to fall short if this is to be a reliable power plant.

I'm not sure how reliable any 1000+Hp motor really is...
