Plenum & Injector Housing Porting

[jss06c6]

Gents,

Thanks to Constantine, I've got a spare Plenum and pair of Injector Housings to port without shutting #473 down. I've read, with great interest, Keith's (KJL) thread on Corvette Forum. My goals are the same. I've got a '91 and my Plenum looks identical to Keith's. However, the one I got from Constantine shows straight pipe nipples just below the TPS, versus the rear one being curved. Is this something to be concerned about? I was also surprised to see that the Injector Housings were "chamfered". Obviously there was an attempt to eliminate a sharp edge at the transitions from the Plenum and the Heads..

I'd like to get a "junk" injector to verify how much I can take off the primary boss. I understand it can essentially be completely removed, just want to get an eye on it before I put a burr to it.. If anyone has a junk one laying around, I'll be happy to pay to have it shipped..

Got everything cleaned up. Here's a few photos showing the chamfers and the injector bosses.. Would appreciate some guidance on the pipe geometry (not sure what these two are, will need to check my docs)..
