best aluminum injector blocks

well its sucking air again. i dont know or even see how it could be the intake but i am going to replace the injector blocks just to eliminate it.
i did an AFR test on my brothers car, his is an O2 car but it is not connected, AND, his car is running very rich. but what i was more concerned with is what his AFR's were at 2500, 3k and 3500. his where all the same, 13.5.
mine gets leaner as the RPM's go up, which i think is due to more air gettting sucked in.

i have seen the blocks with heat insulators, but are those really needed. i am just thinking that adds another gasket and a place to leak. any suggestions on which ones or best price?

oh, i drove it with gauges on for about a month, steady 3.6bar CP. put them on last week and syspressure was down to 5.9 from 6.2 and CP was down to 3.4- 3.5bar. i did a FP test a while back. i removed the input line to the FD and ran it there. the FP's passed the volume test.
