Cylinder head/cam compatibility with LS3
Does anyone have experience with Nightfury 113 cam and Mast 6 bolt 255 cylinder heads combination? Or compatibility issues with Mast 6 bolt heads and stock manifold or other fit issues on LS3?
Thx |

Hmm. Is this a MAST only fitment issue? I just bought prc255 ls3 heads and there is no mention of stock intake not fitting on the website, nor when I spoke with the reps. They are a '6 bolt ready' head also. I hope I don't have to hack up a $2600 set of heads...

Just confirmed with Tyler at Texas speed that there are no fitment issues with PRC 255 heads and stock intake. Phew!

That would be an exercise in futility...
