i just ordered a set of honda 929 itb's off ebay to put on my gsr. Implanning on just cutting a stock manifold and clamping them on. My question is, what manifold will bolt to the head besides the gsr one. I have a LS intake and a B16 intake, i dont wanna cut up my stock on incase i need to go back to stock

 

gsr fits and also the gsr one does
did i mention the gsr

 

I would either buy a gsr of ebay or get a head flange and build one, dont ---- with your stocker because one day you will want to put it back

 

who makes head flsnges in alluminum
