Sounds like you're a maximum hp kinda guy. If you can wait, the AFR 225s will be the hot ticket. If you need to buy today, you can't go wrong with the AFR 205s. I have them and make good power through a catted y-pipe.

Well I am in the process of taking my engine out and opening up to see what the **** blew up in it. So I'm pretty much done for the season.
Anyways, the AFR 225s you say are good? How much more HP can I expect to pick up with these?

are you going with a stock rebuild, forged rebuild, or actually going with a 427?
larger cubes, i'd go for the 225s, and maybe put them on an all out 347 aswell. TTP had good results with 225s and a huge cam, putting them over 500rwhp, but its not much of a daily drive style.
how far have you got with the tear down?

I decided to build a bigger motor on tuesday. 3 days later I had the new LS-2 aluminum 402ci motor (shortblock) sitting in my garage from SLP. $4200 with shipping but it seems like a good deal. I am awaiting my AFR 225 heads now. There is about a month wait time I think, or at least thats what they told me when I ordered them. Just deciding on the cam now. I'd go with the bigger cubes if your going to do the block anyway. I also decided to go with the AFR 225 heads after talking to Tony at AFR even though they were a bit more expensive than other brands. Though I have to confess I seriously considered the Patriot stage 3 heads to save the cash and use it towards a fast 90/90 setup.
Good luck and if you don't go bigger with the cubes the 205 AFR heads would be plenty I would think. Call Tony at AFR and he can help you out.
