Default single plane ms3 ported heads

hey guys , i have an ls1 with single plane victor jr intake low profile elbow. just bought ms3 cam and in the proses of porting and polishing some 241s. everything is going to be match ported. porter says the 241s will flow just under or right with the ported 243s. porting and polishing the intake as well. will step up to a 4150 tb in the near future. will be running a 150 shot threw it. looking to see what u guys think about this setup.

You might have the grind in dome valve reliefs, but on top of everything else that shouldn't be a big deal...I'm running ported 241 heads that have been milled down to 57cc chambers.

My biggest concern is the low profile elbow being too restrictive for you

If you can, look at the intake pans...not really sure what they are actually called....that way you can get your air from a huge area at the bottom of the windsheild by just notching out the back lower edge of the hood.

Install the cam, measure ptv, mill accordingly. More than likely, you won't be able to take much off without crashing the valves.
