does d80e stock heads repond well to porting?

U could probably make decent power with those heads, but they are not gonna be what you want if u are shooting for 400 hp. I am not saying you have to save up for aluminum heads, but if u use those D80e's they are going to hold back ur engines potential.

I ported the e7's and have no money in them, but now I want some better flowing heads. Personally, I would unload the ones you have now and bump up to a set of e7's at least. Put them on ebay for what you have in them and see if anyone bites.

If you want to do it with those heads, go for it. Just hate to see you go and put it all together only to wish you had used a better head the first time around.

400 horses is pretty healthy for a naturally aspirated motor. Is it a 302 or 351 you have? To me it looks like your combo will yield around 260-275hp if it's a 302, IMHO. 400 horses out of a 302 is going to have to spin around 6500rpm. Head flow will probably have to be around 280cfm on the intake side. Victor Jrs, AFR 185's, Ford Racing Z head..... Have your buddy flow test your heads when he is done. You'll know exactly how much power you can make with the flow numbers. 650 carb is perfect. Victor Jr heads with a victor jr intake and a more aggressive cam in the 560-580" lift area with around 260@.050 solid lifter....that'll hit 400! Just my two cents.....

Im a good bench racer.
