What would need to be done to put a 1g head on my 2g block??? Is it even worth it?? Matt

Why is there a STAR kit for a 420a in your sig pic, if you have a 96AWD?
Well anyways, here's some of the steps required for a 4g63 headswap:

not sure about this cause i don't remember how it goes but i'm pretty sure the 2g head flows better than the 1g and the 1g block is better because it's a 6-bolt. so i don't think it would be worth it. but someone else with greater knowledge than me should back me up on this or correct me.

1g head flows more air than the 2g.

The 1g head flows better, but the 2g head can be ported out to flow more than the 1g head. Theres more material around the 2g ports than the 1g ports. So if you dont want to do a lot of work then the 1g head is the way to go.

I've heard that the 2G head has better intake port entry angles, and with a valve job and light bowl porting it is superior to the 1G head.
Port your 2G :thumbsup
It's easier than all of that swap crap, and will end up better
Port entry angles>Port size. In drag race engines you will find tons of raised port heads with smaller ports that outflow bigger ports with lower port locations.
I don't agree with all of the 7-bolt fear :rolleyes

There's WAY more to do before you even start to think about trying to flow more air through your head. Hooking up a boost guage w/out getting a CEL is one of them.
