yeah this is what I am suspecting, because to my knowledge many people here at inliners use these webers with great success, makes me wonder why so many people would buy them if they created no power and had so many problems, because in all reality if a holley 390 made as much as 30 percent more, eveyone would use them hands down right, i mean thats the differnce between 150HP and 195HP straight up, so I think someone might be blowing steam, so I think that I am buying two holley webers when tom gets back from vacation. maybe I will buy their cam kit just to get the valve train parts and all, see when he said sink the valves I thought this was a huge process because they had to pull the seats out, cut in .100 and then reinstall seats and then cut them, maybe I'll get it cut like .070 or something, but I dont want to get too high if compression, or maybe my cam grinder can do just as good of a job and I am being led astray by these guys so they can make a buck off a sucker looking for a dream of unattainable power, any thoughts????
