I'm into these about $700. I accept there may be little to no difference in performance on street, but in that case why did I spend the money on different valves when stock probably sufficient for this level of port job? I'm certainly not one of those who love to throw money at the absolute best or most popular solution, but why in the world would I try to save $100 or so for a questionable result when I'm gonna be into this project around $3000 all said and done?
I wanted to get cams from this guy and took him up on offer to do machine work as well, which may have been a mistake under the circumstances.
If u care about your build and how it runs why get heads done by a no name unpredictable source? Just to save a buck. Thats going down the wrong road.

I'll send you a PM.
Please don't get me wrong here... I have no opinion one way or the other about your guy's work... might be #1 all time top flowing for all I know.

Did you port for looks or performance? You made no mention of the "results" of the port work.
Obviously per previous posts I didn't port for looks, and I understand job may be perfect for my application, but it looks shoddy and I have no way of knowing results until I put everything together at which point it's a bit late to go back to machinist and get anything done.

Again per earlier posts, this guy is not a no name unpredictable source--he has been in business for years, just isn't one of the big names on these forums that does a lot of mail order work. When I first stopped by in January he was working on some custom cams for a personal project of Arlen Ness. As I specifically said, I'm not interested in compromising build to save a few bucks, but I thought cam guy would be most capable of matching up rest of the build. I figured he wasn't going to waste time making it look pretty, but this looks a bit shoddy and wasn't what I expected.
I realize I'm asking a lot of this forum, but constructive responses from people who have seen port jobs from known quantities and have some frame of reference for comparison are what I would really like to hear about. If this is typical of a job done for no frills performance then great.
These are from a well known shop and they were done for good velocity at lower rpm, not big flow up top. In fact they were done to use Andrews 57's with. I don't know if you can judge how well ports function by appearance alone. Put them on and tune it and see what you get. These heads went on a 103 with the 57's and did 109/117 and went over 100 ft. lbs. at 1900 rpm.
I understand on the intake side you do not want a polished port and that imperfections can help with fuel atomization, though opinions vary on whether that's still a factor with fuel injection. Not aware of downside with a nicer finish on exhaust ports or combustion chambers...?
Likewise some say flowbench is not the be all/end all of determining factors, and I understand high flow numbers are more meaningful on high RPM race oriented applications and may have little to do with street performance. But polished combustion chambers should have some less propensity for detonation and carbon buildup. Polished exhaust ports ought to scavenge easier and also have less buildup.
And the question of polishing aside, the pics do poor job showing it but there are noticeable high and low spots.
This wasn't cheap either, and if heads didn't need to be ported any better than this, then why did I need new oversize valves??!!
Sorry don't mean to rant, but feel like I might've been taken.
Bottom line: do these look comparable to what other people have had done?
Looks like a first class hack job to me,,, I'd be pissed!!
If those are "new oversize valves" then where did the carbon on the stems come from?? Thinking I read where you haven't run the heads yet??
I've seen / used heads from some of the best in the country,,, no, none looked like yours...
