Nitrous kit or heads? Sorry for all the posts lately and I am not 100% sure if this is in the right section. But anyways, I have been considering getting heads for a while now and with winter coming up it would be the perfect time to do it. But today I was offered a brand new ZEX nitrous kit for 300$ from a good friend of mine. My question is which modification will be safer in the long run? I am already making 423rwhp cam only, I am assuming I could probably make 460rwhp with heads or more with a nitrous shot. But I dont care about speed when it comes to reliablility and durability. I dont care what it costs to buy a completely safe nitrous kit and have it tuned. So let me know what you guys think about this

Ah sorry, I have a full bolt on, trex cammed WS6. For fuel mods the only thing I have is 42 lb/hr svo's. Also I plan on using a small nitrous shot maybe 75 hp. I like to keep it safe.

75 shot < lol
Heads are a lot more work to use compared to nitrous.
I been considering the same thing. Heads or juice.
Do both. . . . . . Just one first. I am thinking heads. But, the price really depends on how wild you wanna go.
P&P 243's = 700 Bucks or so
Niceset of AFR's 2k+

There isn't a switch for your heads to work.. Go heads now and if you want the squeeze on it later, then so be it.. Also will give you time to save and forge the motor and then you can really give her the jug..

You know my vote..
Intake and heads.... Save the nitrous for later.. If you are already at 423 Rwhp then a nice intake (ported 92mm) and a set of heads like you are thinking should get you REALLY close to 500Rwhp.. Realistically around 475-480Rwhp, but still......
I would do a pump to be on the safe side, but you shouldn't need one.. 100$ is pocket change when talking a nice H/I swap.

Heads will compliment the cam well and give you power on demand. dont get me wrong, LS motors love nitrous, but having to pay 50 bucks to fill the bottle sucks. nitrous has a bad rep for being unsafe, as long as you take the correct measures just as in any mod, nitrous will be just as safe as any other mod. TUNE is key, fuel pressure safety switch, blow down tube, window switch, wide open throttle switch, this all adds up $$$$$$, but when you flip the switch and hit it you wont be thinkign about $$$$$. I would go heads and see what you want from there, you can always find nitrous ktis cheap, many on here for $300 so dont think that deal will never come around again.

Go for the heads man, having power all the time will really be a lot more fun and more reliable in the long run. It'll really wake that motor up with a cam like that. PS: your sig is ******* hilarious HAHA

Sure they add another 40 Rwhp, but look at where they add another 40 Rwhp compared to AFR heads. You will see why AFRs are so
.. Most people look at the peak numbers that two heads like that give you and say that AFRs aren't worth the money.. They don't pay attention to the whole curve.
