Hi everyone,

New here, from the UK. I've just purchased a G20 conversion and loving it so far. I want to do a few performance upgrades over a reasonably long period of time, I'd really like to know what, if any headers will fit this thing as the original headers and exhaust look really restrictive. After that I'm not really too sure, I've heard a bigger cam will help but the heads are really restrictive too?

Any advice appreciated.

Cheers :-)

 

Need a few more details, like what year, what motor, and who did the conversion.

 

Oh yeah, how could I forget that? It's a 1992 350 TBI. As for who did the conversion, your guess is good as mine.

 

Not that it will make a difference for headers, I was just curious. The next issue is what is available to the UK. I just did a quick search in J.C.Whitney, and they have quite a few.that supposedly fit your van. As to whether they ship over seas, don't know.

Truthfully, this is a bit out of my area. It's been many years since I've done headers. Too many years.
