Dilemma....Ported Heads or Ported 92/92 ????????
I have a dilemma and i can't decide what i should do. I will be spending about $1400 for mods pretty soon. Basically I can't decide whether to
(1) sell my stock 243's for ($550-$600) and buy some ported heads (PRC 215's, AFR's,TFS) for around $2000 ???????
(2) Or Run with my stock 243's i Already bought, and a Ported 92/92????
I will be going with a larger cam (235-240ish)regardless of what route i choose. So, don't base your input off my current cam. I'm looking to gain the most power I can on the budget i stated. I know the heads are proven to show huge gains ,but will the stock 243's and a Ported 92/92 show similar gains???
Let me know what your opinions are guys.

Yes True, but i'm comparing (stock 243 heads + Ported 92/92) Vs (ported heads and my current ls6 intake). I know 243's are good for 15rwhp or so and a ported fast is good for 20rwhp-ish. I figure I'll pick up 35-40rwp with the 243's and Ported fast. Would I gain much more with some good heads and running my ls6 intake manifold?

real tough call.
both routes will make great power gains.
if you can honestly afford the AFRs you'll probably make more power with them than the other option.
everyone criticized me for going with the ported FAST on my setup, saying i wouldn't gain much since it was cam only and already had the ls6.
but back to back dyno runs proved otherwise...18hp and 12ftlbs peak and 5-10hp and torque from 3000rpm and up. and that was a home ported intake...nothing $$$.

You're math is off.
Both of those heads are a good bit over $2000. Then you need to factor in hardware, gaskets, and fluids. If you sell the 243s figure out of pocket expense around $1800.
If you sell the LS6 intake and throttle body, the FAST intake and throttle body out of pocket should be around $1000.
There is an $800 difference, and additional labor for the heads.
Furthermore, with that larger cam you want: the LS6 intake is going to restrict power above 6400rpm, whereas the FAST setup will get you another 400-500rpm.
My suggestion would to be to go with the FAST setup. Sell the LS6 intake and throttle body. Keep the 243s, but get a good valve job done and mill them a little. That should put you in the $1400-$1500 range you're aiming for and make the most power of any scenario.

AFRs have your manifold ported and your tb ported and polished, that should be good.

I think I'll most likely go with some nice heads first. It just makes more sense. Then when i have the cash for a Ported 92/92 All i have to do in the future is swap out my ls6 for the fast and keep my heads installed.

I was kind of in the same boat. I had Stock 241's though and an LS6 intake (sitting in garage). I found a cheapo used ported 92/92 (vengeance was doing a sale on there's idk if it ended though) and going to save up for some TFS 220 as casts and play around with those.

The heads are the way to go if you can afford them, by the time you have them installed with tune and you know you want to replace the push rods and rockers you will be tapping $3500.00 You could by a LS6 short block for that amount of money.
Buy the intake and spray!!!

he already has a cam...likely has the right pushrods with it.
no need to replace the rockers unless hes going TFS w/ the altered valve angle.
factoring in things like bolts and gaskets is mute because he'd be doing those things anyway if he just swapped on his 243s.

My bottom end is perfectly fine. I have no need for a new motor and i don't plan to spray at this time. I have pushrods and if i need a different length I'll sell/trade mine for them. I'm getting a full dyno tune after i do the install regardless of which setup i choose.
