Default ported head input

Hand ported on 2.00/1.5 valves with superflow numbers. Shooting for 280-290. What could I sell them for?

You're not going to get **** out of them without results proving they're "as good or better than AI or LE" heads.

You can always throw them on and race me :-)

If you are trying to fetch top dollar for these heads you'll need to provide a full flow sheet AND proven track results. The top two head porters have YEARS UPON YEARS of experience in both trial and error so (not to discourage but...) to assume your home-ported heads will be better than or even AS-GOOD is pretty bold.

As far as asking a price you should know how much labor and parts you have in them and what the competion asks to determine what they're worth. I thought about selling my old home ported heads which I have proven results with them but was afraid of the critisism. They don't look as perfect as the big boys but they work. That's a big problem too people are hung up on appearance.

i will have superflow numbers, thats why i said i was going to spend alot of time on the bench. I am just putting a feeler out there because i know most wont buy them without knowing they came from one of the big 2, and yeah they wont be a proven setup, thats why i want feedback. I should not have put the "as good or better than ai/le heads" my bad, They will be a damn good set of lt1 heads.

Competition is a good thing and you have to start somewhere. I say go for it. I never touched a set of heads in my life but I managed to squeak an 11.6 @116 with them on a stock short block and I know I could have went deeper if I didn't spin a bearing.

Anyone willing to pay a lot for a head based on flow bench numbers alone is an idiot and you will find a LOT of them out there.

The flow bench is a tool but NOT the measure of a head's potential, bolt them on and go racing THEN you will have some meaningful data.

I know bench racing is for idiots, if I had the time I.would definately bolt them on my 355 that will be in the f68 shortly, but I don't. I work 50-60 hours a week the way it is and have a wife and 2 boys. I have learned from a couple genious guys, one even did prostock buildimg for jegs for many years. I do the stuff all day but haven't been in the position to sell any of my work. Basically you'll get a set of sweet heads, that's all I can promise, I'm not asking for respect.

I agree ^^^ Make a test set of heads and let some one try them out to get some track numbers if you don't have the time. Someone that already has a set of your competitors heads to compare with.

Port some and find someone who has a decent combo and racing experience. Let them try them out. Get dyno and track results. It's hard to be as good as a machine but if you have the skill and attention to detail I'm sure one could build a good reputation for hand porting, and there is a market for that.

well a cnc porting all starts from a hand port that gets digitized. All I'm really trying to do is make a good set of heads to sell, I'm not trying to elbow my way into the porting business as an employee at a shop. whoever buys them will just have to take my word they are good, you cant look at a ported head and tell if its good anyway, you at least need the valves, a calipers, and a set of dividers just to get an idea what was even done, and where the verturi % is etc. I will get them done and just try to sell them local. Also just to put it out there, if you guys want a real porting pro to look up to, look up rehr morrison, he has alot of good material you can buy and start doing this stuff yourself, its gets very addicting. Well im off to port a couple super vic II's for some race motors lol. Your input has been appreciated.

If I was a buying customer this is the last thing I would want to hear out of a vendor's mouth.

I have had a few run ins with "former ProStock" engine builders over the years, one of them swore blindly that an LT1 needed a 112-114LSA to keep the computer happy even after he saw my results and I told him I have installed 3 cams in the 108-110 range.

A friend has a current ProStock engine guy building his gen 1 stuff, it runs well but not "that well".

Racing stuff doesn't always translate well to street/strip and being a god with a 10,000rpm BBC doesn't mean someone can port a set of 23degree SBC heads for a engine 30% smaller turning 30% less rpm that needs to also operate over a broader rpm range.
