I almost didn't answer this because there's not enough info to make a valid response ( again, where are the .100 flow figure improvements on intake & exhaust). Also, i don't know what was done to improve the intake or exhaust flow. You are definitely going to have a (seemingly) wilder cam with low lift flow increase. You will have more reversion, true, but, in my opinion, you are going to see a substantial performance increase. Ron.
