The 93 intake is not a step backwards for max power as his looks really good on the porting side of things, but........... for this guy.
Find a 94 fuel rail setup and just get a shop to run a braided fuel line in place of the hardline crossover so it can work on that nice ported 93 intake. You can find the complete 94-97 fuel rail setup with the FACTORY regulator (dont buy into that aftermarket junk regulator) all in place then just a little fabrication could have it working on that 93.
On everything else listen to these guys as they have ripping cars and most are street cars.

If I dig I think I have a complete 94-97 fuel rail setup, the 93 SuperStock intake I sold ended up on a 94-97 fuel line car so maybe you can contact him to see what it takes to get it running on your setup. Also I think your going to need a 94-97 throttle cable bracket to make your intake work on your ride. I think I have a pile of those also so I will look for you as this will make the conversion easy.

As long as the intake ports are not bigger than the heads intake ports he should be good to go. Even on a very mild combo just getting rid of all of the plenum restrictions that are direct behind the throttle blade holes would make a nice gain. If you look into his 93's TB holes it has some nice work put into it and im sure LE tapered the ports correct so its not like some of those ebay super hogged gasket matched intakes lol.

Thanks for the comments guys i appreciate them despite them more on the critising end of it but you guys have built them time and time again. As for the intake i got it with the tb for a great price and was just going to make my own fuel lines to mate up to it or buy the speed inc kit. Ive slept on it and i think im going to try and fetch some cash for my AFRs and try and find a set of stock ported heads that i can mill down to 56cc and get up to 11.4:1. A buddy of mine is looking at selling his in search of actually a 64cc head for his blower setup. Not really sure what a set of ported stockers go for and what do for a trade plus cash?
Question will the longer valve make a difference and are these springs interchangeable with HR and SR cams or he likely changed them out when he got them and put them on his car? My friend bought them off the guy that made the posting i quoted and just had them cleaned up and a valve job done so they are ready to bolt on and go. NOTE pics posted were before work was done. I figure all i will have to do is slighlty mill them to 56cc and call it a day. This way im gaining a full point in compression and the heads wont be as overheaded and match the the cam alot better. Worth it?
I have a set of ported LT1 heads. The porting was done by Hi Flow Heads in Alsip, IL. They have a reputation of doing some great work. They are 180cc intake runners with 58cc combustion chambers. The previous owner had them on a 355 w/ a solid roller cam and went 10.76's on motor and 9.8X on nitrous. Here's the basics:
LT1 castings, 180CC intakes, 58cc chambers.
2.02/1.6 Ferrea 5000 valves .100" longer than stock
Crane "10308" springs
7/16" screw in ARP studs
Comp Cams Guide plates

yep your dynamic compression is what will mainly tell you what gas your going to be running......a friend of mine just built a 12.2:1 motor and with a mild tune i got it to run on 93 just fine.....my old 355 was 11.3:1 and that ran just fine as well.......hell with a really mild tune i can run my 14:1 385 on a 50/50 mix.....its all about the tune and the cylinder pressure......static compression just kind of gives you a ball park of where the pressure will be......run your dynamic compression #'s and see what you come up with.....

either way then why does every tuner complain about compression and 93 octane to safely tune it then? Compression is to high its way harder to tune. Are you still running your knock sensor or is it completely turned off?

I am fortunate enough to have a job that encourages me to surf the internet. Everyone should be so lucky!As for the tuning thing, a good tuner doesn't complain about a setup; they make the setup work (within reason of course). Just because dynamic compression may be high doesn't mean a tuner CAN'T tune it. The ones that complain about it aren't good tuners. Bryan (from PCMforless) asked me for my SCR and DCR when I pulled onto the dyno. After a few minutes discussing my combo, he said "no problem." 30 minutes later he squeezed out the numbers below without 1 degree of KR. My KS is untouched and still works.

Yes as for tuning I understand that and know what your talking about. Many tuners just cant get the tune to work out. Many shops/tuners just cant/dont or wont spend the time to to the tune the damn car the way it should be. My buddies car had a similar setup to you and they had turned off the knock sensor cuz they couldnt get it tuned. Then had to run mixed gas off about 100 octane when mixed 50/50. They then turned on the KS and everything went better. But I still think they could have gotten it tuned with the KS working on pumpgas

Instead of changing everything, spend the ~150 to mill your heads down to at least 60cc. A 5cc mill will not effect your intake seal - that is only a .020 mill.
I see no reason at all to sell your intake or heads. 93 intake is a better foundation then 94-97. Sequential/batch means nothing - the drivability difference is not noticable and their is no power difference.
Those little 190 AFRs are not too big for a 350 either - just mill them down to up your CR and you'll be fine. They are not stock castings - I am willing to bet that even at over 290cfms and fairly large chambers they will still make more low end power then smaller ported stockers. No reason to downgrade on the most important part of any build, the heads.
True, you are under cammed, but emissions sucks - not much you can do about that. At least try what you have before you get rid of everything. Worst case scenario you can sell what you have and try something else.

They are 64cc as they sit, and even if i do mill them to 60cc it will only put me at 10.8 which is minimal. If i go for my buddys heads the 58cc will put me at 11.1 and if mill them to 56 it will put me at 11.4 which is a full one point bump.
