Lower intake runners are bit bigger then head runners...How bad is this?

I have the systemax 1 intake wich goes with the stock upper intake...I also have a set of Powerheads, however, the runners on the lower intake are a bit bigger than the ones on the heads...The lower intake mates with the FEL-PRO 1250 gasket perfectly while the heads are a tad smaller...This intake was recommended to me by the owner of Powerheads, however, my concern is that I have a bigger opening going into a smaller head runners...so should I be expecting turbulance when the air enters the heads? I don't think velocity will be lost since the runners are the same width as the heads but it seems as though the air will be hitting the lower or upper edge of the head runners...any comments on this?

UPDATE as of 4/19/04: I measured the height of the runners on the Powerheads and they came out to be 2.0 inches...than I measured the runner's height on the lower Systemax one intake ant it came out to be 2 1/8 inches...I know that the heads fit a Fel-Pro 90361 gasket while the lower intake takes a Fel-Pro 1250...SO is 1/8 of an inch something to worry about? WILL this cause turbulant air once it enters the head? From my perspective the 1/8 of an inch "wall" will be on the upper side of the head runner right by the injector area on the intake...CAN someone PLEASE help me out...I need to know if I have to open up the heads...NOT sure if that is worth it...I NEED SOME HELP...thanks guys...

Thanks for the good news...wasn't really sure if that would be a problem or not...maybe now I can sleep better...lol...BTW: I like the new rims you're getting...saw the pix on the corral...

Yeah I saw your other thread...I'm sure you'll find something else to buy...you're never done even when you think you are...

O.K guys here's what I found out...
Lower intake: Port Size: 1.97" height; 1.08" width...fits the FEL-PRO 1250 like a glove...

the POWERHEADS port sizes I don't have but it does fit the FEL-PRO 90361 gasket...Does anyone know how big that gasket is? I can't really measure the heads since I am away at school and they are 75 miles away from me...am looking on-line but no luck thus far...

That's just it...I just called the company and I was the first one to tell him the systemax 1 intake had bigger runners than the heads...he did say that if it is by a little bit it shouldn't matter, however, the ideal thing would be to have a smaller intake going into larger heads...just as I thought...I just want to find out for sure how big of the difference is in the height of a fel-pro 1250 gasket and a fel-pro 90361 gasket...just to make sure that what I think is a little difference in hight actually is a little...and not alot in terms of cars performance...

come on guys toss me a bone here...I guess I'm just retarded when it comes to looking up info...I tried...I really did...

PLESE READ MY UPDATE AT TOP OF PAGE!!! thanks guys...

the measurements are:

head runners=2.0 inches
lower intake= 2 1/8inches

my mistake in the previous post...

ttt...anyone else have an input...
