It just always amazes me that people forget what & where these heads came from and what they have done in the PAST and a Distant past at that. 410" Alcohol Sprint Cars (750-850hp) NHRA ProStock Truck 358cui and 7.50/180mph 1/4 miles Turning 10,500rpms. Nascar Cup and Busch Series 358cui. I have a set of W9-RP (I know they are a Bit Different) but the shop that ported them claimed 400-425cfm depending on which bench they were on. Also told me I could probably get another 25cfm if I sent them to Reher-Morrison and let them run their W9-RP CNC Program on them. I personally would like to see what the W9s are really capable of. Like a Few others I have a NIB set under my bed. LOL! I only know of 3 small block heads that come even close to the W9's. SB2's, Mozez, and P7. I wouldn't even consider the P5-Hemi in the running. How available is it and did they ever fix the Leaking Issues.

I did read the entire post and I personally don't see any way to get those kinds of numbers without moving/changing the "factory" paramteters. Rolling/angle milling helps but you need more than that. Next you will say it uses 3/8 stem valves... lol Just kidding, keep up the good work. It is nice to see a thread dedicated to hard core smallblock cylinder head developement.

It's so not Yellow and/or ST of you (and Jeff and Dennis) and I for one appreciate it. I don't recall any SB inline-valve head for any brand matching your high lift numbers. I'm looking forward to your on-track verification of these. I've never done any W8 or W9's, but always "heard" the W8's were better for a "big" application. Do you think you have enough material in critical places to just digitize and CNC it? One usually has to allow just a bit of cushion due to core shift. And just wondering, if not another secret, have you modified your port for a longer valve? No matter, good to see civilized dialog going on instead of chest beating.

If my post was taken as being a critic... someone took it the wrong way. I am only stating that I would love to see the head on my bench to see what it does. If it goes 475 @ 60" of depression corrected the man hit a home run!

The port hasn't been alter for a longer valve...the issue with CNC'ing is one I will need to work out when I get to that point...I am well aware that there are some thin areas right now that could prove to be an issue....8's would be better as they have thicker castings and would be more forgiving...not necessarliy sure that making the port larger would be beneficial but that would also be an option with them....unfortunately I have a set of 9's so that is what I will be transferring the design to....one way or another...once I am satisfied with the results....

If you mean flow @28" mathematically corrected for 60" then the number should be nearer 660....450@60" mathematically corrects to 307@28"...I realize that the higher depression may/will cause conditions in the port that may/will change flow levels just wondering exactly what you meant?

I don't mean "critic" in a negative sense. If I reset the bar on flow in a well known specific casting, I'd expect some critics. I'd expect to eventually need proof, if not on the bench, on the ET slip. I'm just happy to see no one is throwing rocks this time.

I have not been playing with them for a while ...I am pretty satisfied with the port design as it was when this post was written. I recently bought a set of raw w8 castings and my plan was to see if the port would be easier to adapt to the 8's over the 9's. Once winter sets in I plan to dig them back out... as well as the untouched blue plug 5's I picked up and the 2's on the car right now......work schedule permitting.....thanks for you interest!
