I have a set of M2 track 1 227's now and was thinking about making the switch to the M2 18x std port heads. how much hp gain do you think their would be on a 420 with 11.85 comp? i was told 50-60hp. what are your thoughts on these heads?

Although I have no dyno sheets, only track times show the 18X spread port heads and intake I ported gained roughly 100hp by using the 1/4 ET to HP figures.

The old heads were Track 1 heads that flow decent but not the best.

I would think with the complete matching intake and a well designed motor you should easily see 50-60hp. I was very impressed with the on track numbers over the tiny pushrod pinch restriction these heads use to make them work with standard valve train parts.

Note: These were my ports, not M2's. I am not sure how they compare?
