ported head input
I'm really bad at this forum debating thing. Ill get them done and well see what happens. Im sorry I word things badly. I honestly do not mean to ruffle feathers.
As far as my boss goes, he did pro stock 10 years ago, we do so much stuff now and it all blows expectations away. Mostly usmts, and nasty street motors, but have done all kinds of things, even alot of diesel stuff. We even did a 533whp srt4 caliber not too long ago, got to ride in it too, kinda scary lol. We stay well rounded I guess lol.

No one is trying to knock you here, but the LT1 platform is an extremely application-specific thing to deal with. Anyone who has worked on one at any sort of a technical level can tell you that. This means that someone who is good with them, has years of experience specifically working on LTx applications.
This casts doubt on anyone who makes unsubstantiated claims derived from experience with Gen1, SB2, or any other platform. Any engine guru with previous other SBC expereince can go in, do a decent job and get results most here would call mediocre to good with the LTx platform. The guys doing the really stellar, standout LT1 work, though, are the guys who have tinkered with these things ever since they were still sitting brand-new on showroom floors.
Your best bet is to port and set up a pair of LTx heads, pick a good cam, bolt them onto a car and show us results. That's what LE and AI were doing way back when they got their respective starts. Claims can be argued, results can't.

I hope I am not coming off as saying you couldn't do good work.
With almost 12 years on LT1 forums I have just seen a lot of "great" vendors come and go and a few mediocre ones thrive on little more than kissing the *** of anyone who calls them. Some truly good technical people fail on lack of business skills often taking in so much work they can not complete it in a timely manner then getting incompetent help to try and resolve the backlog.
Transmissions are a specific area I have seen a lot of companies pop up be considered "great" for a short time then the **** they built all begins to fail 6months to a year down the road. and they manage to excuse it for a little while still selling junk because everyone who bought in the first few months was happy at that time. Then often times guys that were outspoken about how great something was are too embarrassed to come forward with the failures because they know they lead others astray.
Far as the CNC starting as a hand ported master that is true BUT at the same time the hand porter can spend 40 hours or more getting a few ports just how he wants and then digitizes them and reproduces them exactly. In a port injected application consistency is more important than a TBI or carbed application and we have it very well documented just how substantially the "good" popular hand porters work varies. Don't get me wrong full hand porting CAN be very good, but it takes TIME to do 16 ports consistently by hand and it is still nowhere near CNC level consistent, TIME IS MONEY and to get truly good consistent hand work will cost more than what the LT1 market will pay.

Well finally some good input. I agree with what you two are saying, maby I should do some research before I make a claim. I'm just calased from the stuff I end up fixing from guys who are "the best", I end up assuming when I shouldn't. I would like to see a good motor with an ai or le heads and cam setup on a good bottom.

Well said sir.
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.

Holy shart, I agree with do wayne 100%! Whats this world coming to
I'll be a gunny pig this winter if you will hook me up with a good price on a set, I'm planning on heads cam anyways. I can drive pretty well too (12.5s in a bolton m6) so I'm sure I can bring out the full potential of your heads. Put them with an le or ai 224-266/230-232 cam and "let's see what this baby can do"
