8.5k would be a nice +18% on 7200rpm. However, the head does not flow enough for the stroke and it will choke before 8k. The power can increase until the flow exceeds sonic speeds when the power drops abruptly.
care to show your working out of how the head doesn't flow enough AFTER porting+valve job? The only before and after dyno we actually have of head modifications alone show the ported head should make power quite well with a raised redline.
piston speeds are not too fast at any case
8350rpm on stock stroke, stock rods, is 25m/s (little below 5000 feet per minute). so again, 8000 should be a nice reasonable rev limit to aim for i believe.

" I am so far pleased but am running into a constant issue with AFRs. My banks are always at least one point different. i.e. one has 14.7 and the other is 15.7. I posted my latest log for people wanting to see. Has anyone else with a similar car and kit experienced this and if so how did you resolve it? "
I also hate when you get stuck behind the morons that are causing all the traffic then when you blow past them they act like they weren't doing anything wrong. Like goddammit did you not see the line of cars in your rearview mirror?!
Ha! No doubt. Good addition. I should add people who appear to be clueless/don't pay attention to my list. It amazes me the number of people who wouldn't realize they ran over a elephant if it didn't spill their latte.

Ha! I think every place has bad roads. The best roads I've ever driven on were in Germany. One of my clients apologized to me before I had to drive between two cities about how bad the road was - in 200km it had max, two potholes. Now those were the only two potholes I saw the entire trip, but that made me laugh. Clearly they've never driven in the US. "
