Looking for a set a heads on a budget. Looking to spend around 1500-2000. Setup will be 408 10.5-1 compression, ms4, not sure on intake yet. looking for either used or heavily ported heads. Any suggestions on ported heads vs out the box afr 225s?

Looking to spin around 6800 rpm threw a m6 and 615 lift cam, around 550 n/a hp..

I have seen great results lately using the Edelbrock heads ported to 245cc. One of which running 12.?:1 around the 560rwhp mark. They will probably raise your limit a bit but why not spend a little more to get alot more performance.

I really want a high hp turbo setup but it cost alot more than my single turbo for the mustang. So that being said, what heads would you prefer than? With a cam similar to the ms4(but a lil bigger 650 lift 111 lsa, with 11to1 comp, i think it will roll hard. I want to see if i can pull575rwhp threw a m6, i might have to go 427 big cam, intake/heads..? I was thinking ported fast with afr 225s but do you think there werth it N/A?

You can get that much power or more out of a LS3/6.2L block with the L92/L76 setup for a lot cheaper then what it would cost you to go the route you are looking at.. Just get the stock heads ported. I've seen the #'s on the stock heads and if I remember right they flowed somewhere around 350cfm @650 lift.

We've had PRC LS6 & 6.0L heads on customers 408cid engines past the 1000rwhp mark. If your looking to save $$, I'd consider a stage 2.5 PRC LS6 head. We can set it up with a 2.04/1.60 valve combo for the standard stage 2.5 price. That setup will work really well & flow good air on a 408 short block. I've personally seen the standard stage 2.5 ls6 support past 500rwhp in 408 applications.
