Purchasing New Heads and Intake soon, few questions first.
Alright like it says i want to get new heads and an intake. I asked this before and i was recommended the AFR 165's, and i have a few questions about that.. In Missouri i don't have to pass emissions so i am wondering should i go to the 185's instead? And why or why not.. Also when purchasing these heads will i need to get any other parts? I have been reading and reading about these things but i can't seem to tell if i will NEED these parts or they are just replacements for what i have ect..
Now for the intake, i was also told that i should go with the Edelbrock Performer RPM II, and i plan to do so hearing good things about it, now what I don’t know is will i need any extra parts for this? as far as i can tell no, but i would like to double check with people who have these parts..
Hope it's a good combo!!, any other advice would be great thanks
Anyway, the heads themselves don't create more smog, they simply flow the air. Heads do contribute to a poor smog test by flowing air more or less efficiently in certain RPM ranges. Smart engine builders select cams that work best in the range that the heads flow the most air to maximize their combination, and many times on the high flow heads, the cams that are needed to work with it are designed in such a way that they wouldn't pass smog because there's too much duration, overlap....whatever.
Having said that, those 185's are drilled for smog, and will pass a smog test if you have a clean cam, regardless of if you want the engine to or not.
as far as i know both AFR 165's and 185s are smog legal, the only thing that you would do differently if smog check is not an issue for you is install these threaded inserts into the smog holes and remove the smog pump, alot of people just use bolts but in the front those threaded inserts are necessary to be able to mount your accessories correctly

This is a flow chart for heads that could help you out a little better. i have the edelbrock performer rpm intake and victor jr heads and i dont remember having to get any addition parts cause i did a lot of mods all at once instead of just heads and intake. Also, i use a x303 cam which seems to be a good combo with the heads.

Well to be honest i dont know exactly what to look for.. and that chart just laves me clueless, but i go off what other people tell and what i read on here... So any information on what exactly it is i am looking for would be great.
too be honest i would just like to be able to find the best price/ performance heads, well more or less the higher end performance for later upgrades like a super charger, and what not.
Well i am 17 years old, i am still learning about cars and what not, so i have tons of questions in all honesty.. but my goals are i would like to hit 300-500hp ( big goal gap so you cant be disappointed)
The budget well, if the part is worth the price in performance i will get it, but im no rich man, i would say for a few thousand.. lets say 3,000
the car is a daily driver, but i wouldn't mind taking it to the strip every now and then either..
And i have a few questions about super chargers and turbo, well if i were to get a super charger it would replace all the heads and intake correct.. Would turbo do the same?? I really have no idea and don't want to sound completly stupid but.. My step dad use to be a mechanic and i try not to kill him with questions all the dam time..So any info there??
depending on the supercharger, something like a kenne bell will replace the upper intake, but something like a vortec works like a turbo but driven by a belt. neither replaces heads, or lower intake, a turbo replaces headers, with turbo manifolds.

Well the budget is for now I will obviously have more money later on for more upgrades.. I have cold air intake and ud pullies and Ford motorsport headers
I will also be adding gears and a off road h pipe
But should I go with the afr 185s or 165or is there anything else I should look into??
And for the heads and intake is where my budget is about 2-3 thousand sooo any ideas would be great

One problem I see is that people plan for the "not to distant" future and want to run combos that will not perform to their potential now. It's like buying shoes that are 2 sizes too big but planning to grow into them. Yeah they fit but they just don't work right NOW.

Explain, the idea is to get H/I/C after i put in off road h pipe and gears... the cam i have been reading to get is either a custom grind one or a tfs stage one...
Also would i be able to run afr 185's, reading other threads the 2.020 intake part may be too much for my 302?? I am not positive but when we bought the car the guy said it was bored over .30 so would i be able to or no??
