Likely interchangeable.

The 2g has a better head.

Do me a favor. Go on Welcome To Extreme PSI and look at the applications and part numbers for DSM heads according the parts in question. You'll find the answers you're looking for. And you'll have done it on your own! Yay! Good for you!

2g head is better. 1g has a way better intake ports (more air = more power). 2g. now i cant stop laughing and im starting to cry a lil. but anyway your answer is yes all (cams,valves, springs, guides) are interchangable. a 1g head can be modified to work on a 2g blockas well.

When you get done laughing can you show me proof to why you think that a 1g head makes more power? I dont know why people are going from 1g heads to 2g heads recently if 1g heads are better especially people that are racing.. I think you are alittle confused with the (more air=more power) comment.. Why would a 2g head allow any less air? I would rather have an intelligent answer..

It's been proven a 2g makes gobs of power and has better velocity. And un-ported at that. A guy named Kiggly comes to mind.

That's because all the questions can be solved in 1 minute worth of searching. I for one, will not enable laziness. God forbid I encourage someone (while being a boner) to do something on their own. All this spoon-feeding is old.

yes the parts to swap from a 1g head to a 2g head

if guides are needed, just buy new ones, and have a decent shop install them, a Valve job will need to be done at this point too

How to change Valve guides In a 4G63T head

changing guides is not as simple as it may seem, if not done correctly you can damage the guide bore and ruin the head
Also the guide bore may be streched and the use of an oversized guide will be needed

2g head out performs 1g head stock for stock. Plain and simple. Off topic i know, i just had to jump in haha.

More volume=more air=more time to fill. Nothing wrong with a 2G head in fact the only thing wrong is not going with one. The smaller ports (which arnt that much smaller) give greater velocity which gives you more off boost power and slightly quicker spool up. And no a 1G head cant be modified to fit a 7 bolt because theres no need to the holes for the head studs already fit its the 2G head the need the holes opened up 1mm. Let me know when your done laughing ill get you a coloring book.

Someones got it. Dont forget about Joe at SBR or Curt Brown doing it as well. Contact either of them they are willing to tell you about there experience with a 2G head and the difference they have noticed.

I dont think its necessarily the port size is it, but more the port design, with the 2g head being more of a direct shot at the valves and the 1g head hitting a corner first.

Both has something to do with it. The port size makes a big difference with the velocity but the 2G head also as a much better design with air flow all together.

Bigger isnt always better. If that was the case I would be running around with a big block chevy with all the retarded hillbillys in my area.

the only thing stopping me from saying what i really wanna say is the moderators. this isnt bash time. im a 1g man and i stay strong with my 6-bolt. maybe the flow path is better on the 2g head but to my understanding is that the 1g head has had the most availability for performance options like the throttle bodys beeing bigger from the factory. im just saying. so if you still wanna continue to walk funny like u have sumthing up your azz. go right ahead. your just a high school drop out living in your parents basement. your a cyber bully. i have better things to do then argue with everyone whos just trying to put a fellow dsm'r down. ALL THAT REALLY MATTERS IS THAT WE BOTH RUN A 4G63 IN OUR CARS. if you dissagree then reply but send a pm and not posting to get new members jumping in on the convo. they dont need to come to this site and see all of this going on and make them think its ok. then they get booted or they get put down and hurt there feelings as well.

Really?
Say what you want tough guy I can handle it. Sorry not a high school drop out you need a deploma to get into the Marine Corp and I have my own house so no basement for me just use there garage for the DSM sense I don have one and dont trust the neighborhood I live in. For someone claiming im a drop out your grammer is shit so maybe you need to shut your mouth and read the rules. Maybe if you wouldnt have gave a retarded reply I wouldnt have gave a shitty comment. Thats why I only gave info to help others instead of just an opinion and how I know its not bullshit is because I have talked to guys like Kiggly and Brown who have proven it. Your right we are all DSMers so lets get our head out of are ass and work together giving TRUE info and start boosting.

PS: Sorry if I hurt your feelings.

You can put a 1g head on a 2g without any other modification, although I would advise to get a different IM.

And the headstuts are totally dependant on which block is being used. You also don't have to bore out the headstud holes to do it like someone previously stated.
