cylinder heads?

What cylinder heads flow the best?

2.0 SOHC, DOHC

2.4 SOHC, DOHC

In stock form or potential? I think they are all prettly much the same stock, maybe the following highest to lowest?

2.4L Turbo DOHC
2.4L Early N/A DOHC = 2.0L DOHC
2.0L SOHC Magnum ('01+ R/T)
2.0L SOHC

Slight differences in manifolds earlier to later and by body style as well.

[danristheman]

Well both stock and potential. Port and polish, bigger valves, etc.

I think the 95-99 dohc had bigger exhaust valves than srt head.

Correct, but the SRT-4 heads are supposed to flow better

The 95-99 heads had oval exhaust ports, but larger valves. The SRT-4 heads have square ports, with smaller valves. Put the larger valves in the SRT-4 for the best flowing combination.

Cool

What about +1mm in the oval port?

[tvanlant]

Yes, +1mm exhausts on the early heads are good too. As good as these heads flow on the exhaust side, the standard size ('95-'99) is usually more than plenty. But if you have the money for valves & seats, why not!
