I'm putting together a 306 as follows, need suggesstions on heads given my budget.
306 roller block
windage tray
Stef's pan
speed pro pistons (hypers)
comp cams 274 HR
performer rpm intake
custom Biggs 650 DP
FMS BS FW and Damper
CF DF Clutch
1 5/8 lontubes with 2 1/2 exhaust
I know a guy on another forum who is running the exact same combo with edelbrock performer RPM head (unported) making 419 FW HP. He has access to a dyno where he works so he's been able to do all the fine tuning as far as jets changes/ timing curves/ carb spacers/ etc...He pretty much narrowed it down to where it makes max HP. He is willing to give me all this information which will save me quite a bit of guesswork. The only thing different between our combos, engine wise, would be the exhaust systems.
Now, I can pick up a decent slightly used set of RPM 2.02 heads for about $900. This is what my plan was and I was also considering a small shot of nitrous, maybe a 75 or 100 shot once everything was in and working.
I have also been tossing around the idea of forgetting about the nitrous and simply spending that extra $$$ on AFR 185's instead. Of course they won't make 75 more Hp over the RPM's but in the long run I think that may be a better idea. I've never messed with nitrous but it seems like it wouldn't be worth the hassle of setting up the whole kit, messing with the fuel system, dealing with the wiring, refilling the bottle....for as little as I would use it I just don't see the point.
I guess my question is, is it worth the extra $400-450 to get the AFR 185's over the RPM's? and rule out the possibility of nitrous? Or should I just stick with the RPM's and get nitrous If I decide I want more power in the future.
To give you an idea of what I'm trying to accomplish, I am looking for low 12's, shouldn't be out of my reach N/A with the RPM's. this is with a T-5z, 4.33's, locker, on 26*10.5 e.t. streets. car is a 68' stang, weighs ~3100
