Marty Thanx for the response. You R right the headers were 'sposed to be 1 3/4" not 1 5/8" I will check OD... I will put bungs on collectors as you recommend, however Steve Wong sez I don't need an 02 since passing smog is not an issue.
Steve is gonna do a custom burn for me, dyno and all. I will put the bung nuts on but not drill the collectors until I need to, if ever.
About the injectors working within 99.9% efficency.............. I sent my injectors to RC Engineering to have them match flowed... OMG... I am sure glad I did, there was as much as 8% difference across all injectors and a couple had faulty spray pattern!
Now they are all perfect and are within .001% of each other, money well spent.
Thanx again.... Hey are you going to GAF?
