Speaking of W2s

Agreed. The big flow numbers up top are not needed for the target goal. The numbers look good. Also @ 10.3-1, the 92/93 octane will do. At this ratio and a iron head, you have to be careful not to run to small of a cam. Which I don't think that will be a issue here today with your goal in mind. You probably already know that the more cam you run the more cylinder pressure bleeds off and this the reason why there is an increase in ratio to begin with.

All things considered, I think your on the right track. Now it's up to the cam to complete the job. For sure, go with the Solid roller for the best area under the curve and power output.

For surely try and take advantage of the flow ability of the head.

I agree with this. But don't get caught up too much in flow numbers. I've had my W2 heads on 2 different flow benches and both were very different. As long as the port job was done well, those heads will make some power. There are some things that aren't going to show up on a flow bench but will be realized in a live motor. Also +1 on the bigger cam. I'm running 11:1 on my iron W2's with 91 octane in 100 degree heat with no issues yet. Running a fairly healthy roller cam with some overlap in it.
