Hi i bought a used mini ram and went to install it today and i'm having trouble getting the middle bolts in.Obviously i can't use my factory tor-x bolts so i went and got some boxed head bolts.But i still can't get them in.On the drivers side it looks like its grinded out a little from tpis but not enough and then nothing on the passenger side.Do i need special bolts or grind it out or am i just stupid. Thanks for your help.

 

I have just been looking at some pics of other peoples's mini ram's and mine is different.I'm wondering if maybe i got an older intake or something.It doesn't have the opening in the middle of the intake like the other ones i seen.

 

Call TPIS. You may have an older casting that is not made for your type of heads. Are your heads center bolt or parameter valve cover bolts?

 

There centre bolt heads.I'll give them a call.

 

I believe the later ones are "air gap" as in a space between base and plenum.
What about socket head (allen head) cap screws ?

 

Get some ARP intake manifold bolt set. I think I know what you are talking about, the Miniram has small "pockets" for the mainifold bolts. Im running a set of ARP bolts on mine and have ZERO issues with it. They have a 7/16" hex head on them kinda like header bolts.
