would 30# injectors be too big?(I have some 19#, 22# and 30#)

The top edge of the TPI intake will just barely reach the top of the ports on the ...034 Phase II Bowtie heads. It didn't look like to me it could seal without building up the top of the intake ports on the stock TPI intake.

In the end, I sold them and bought some TFS 23° heads and an aftermarket intake so I really can't say if the Accel intake would have matched the Bowtie head ports or not. Might want to check on this. (I do have a TPI intake with $50.00 worth of weld at the top of the ports but it hasn't been milled flat yet, (and probably never will by me).)

They really are a pretty old technology as far as flow goes. But, they do sell pretty easy and for a preminum price too!
