He's also done a set of heads for Brian Pomeroy. Did they come out as good as the "Sean" heads or better yet could there been improvement...you bet. Brian paid good money for the work Trevor did and the port is HUGE. The valve is also HUGE. Im not sure what hes trying to accomplish but it would have limited Brians potential for sure on what he could have made and really ran like a dog. I've got to see the heads in person and on the flow and wet flow bench. Ive seen his valve jobs he puts on the LS1 stuff. It leaves alot on the table for what was paid for Matt.
I hold Trevor on the same level as Lloyd Elliots work. Its hit or miss for what you pay for.

If done right, a bigger port can work very well.

Chris had the suggestion to flow the heads before they got too serious into the lower end build up and found that out.

Chris, flowed them on the wet flow as well and corrected some things. They dont stall now til right about 780 lift which is better. They picked up some flow doing more modification on the short side radius. They will make power now but I think Brian's changed his mind on using the heads to find out for sure.

It's common for a head porter to get bad flow test results from other shops. It happens to all of us. I have personally flowed several sets of Trevors heads and they were very good.

This is exactly what I was trying to avoid when agreeing to disagree. If you are calling me a liar, I dont appreciate it either way. I have no reason to lie and neither does Chris. We both shoot it straight like we see it. Whether something was good or something was bad a flow bench will tell you just flow. It wont tell you how it will perform on the track. He saw things that could "honestly" be fixed and stuff that would leave power on the table. Flow benches are a measure of change. If you have the right numbers where they need to be then the power will be made. I understand the tactics some use to get business. Business isnt what he needs LMAO. Get back on topic now.

V6bird, I'm not calling anyone a liar, so let's make that clear.
Conflicting flow numbers are a part of this business. It happens every day. The final judge of a head is its performance on the track.
No two head porters think or port alike. That leads to a LOT of criticism between head porters. They see things they don't like about a competitors head and say that those things are "wrong" when in fact they may not be. You have to also take into account that many head porters are arrogant and just plain primmadonna's.
I'm used to people telling me I'm wrong all the time so I'm ok with yuor disagreement, but please don't think I'm saying you and Chris are dishonest.
