Lighter wallet makes the car goes faster, right?
Yes, weight reduction

Reason enough to procure injectors to replace injectors that are currently working as designed?
If it's newer, it must be better. Placebo effect of modifying engines.
You have a crystal ball that tells you his injectors are working as designed? It is highly unlikely that 25 year old pintle injectors are still working to original design spec/flow and pattern.... I appreciate he didin't ask about replacing injectors that have been determined to be an issue.
Sometimes, yes. The design & technology of the composite injectors is better than the pintle design. Just because a manufacturer continued to use them doesn't make them any better.
Not really sure what you're babbling about right now. There are modern metering orifices that produce the same spray pattern as an 8V pintle style injector. Clearly this topic is beyond your comprehension.
We're not just talking about the specific nozzle design. Although I still would choose the 4 nozzle over single, less opportunity for clogging the pintle design is known for. Why stick with the clunky old units when you can use newer technology, if one is replacing the original crap.
We get it. You like to regurgitate stuff you've read on a forum. Clearly you have no first hand knowledge of characterizing a fuel injector. You really don't seem to get that there are modern injector designs that have the proper spray pattern for an 8V head. None of what you recommend has that. It's really that simple.
OK, so you or others you are aware of have performed dynamic testing that indicates only the spray pattern of pintle design is appropriate for 8v intake ports? Have you also monitored individual cylinder exhaust temps for deviation? What criteria are you using to establish your assertions? I'm genuinely interested.
I'm using the composite on my 8v, with no indication of buildup/deposits in the lower runner section or head ports. I've had it apart several times since I switched. I don't have individual egt probes in the header runners or other means of establishing that the switch may have caused deviations in individual cylinder performance though.
Port soak?
I get that the metal of the intake or deposits on a valve could absorb fuel, but is fuel soaking in and evaporating out with each valve opening?
would that make a significant difference? wouldn't it kind of be averaged out each cycle if rpm is steady?
Any good references that explains this for a neophyte?

Do you have addtional info on the GM injectors you used I can use for reference in my search?
