[88fox]

I have a 88 5.0 which i want to get new heads for it. I have the basic boltons on it including edelbrock performer intake. So my question is what heads should i go with that would go good with my intake and im going to get a E-303 cam also. Im want to achieve about 400hp at the crank so i dont want to get something to radical and it all being smog legal in CA..... thanks for any advise you guys can give me

If you're serious about getting 400hp at the crank from a 5.0, the parts you've mentioned won't get you there. Here's a heads/cam/intake combo that will though:

TFS TW or AFR 165 heads
CompCams XE270HR-12 or AFM B-31 cam
Holley Systemax II or Edelbrock Performer RPM II intake

You'll need other supporting mods like CAI, 76 or 80mm MAF, 75mm TB, pulleys, long tubes, midpipe, exhaust, 24lb/hr injectors, 190 or 255lph fuel pump, chip tune.
Don't know if it'll be smog legal in CA though. If not, you might have to either settle for a 370hp (crank) 5.0 or build a 347 stroker to get 400 crank HP.

AFR's are the way to go
