Quick question: what’s the length of the new stud and what is the length of the stock one?

Thanks,

Az

 

the stock one is just a plug. the length is, well secret, lol. will pm ya since you got a kit coming anyways.

 

Good mod.

 

Good stuff scott... how was ur testing today ??

 

There is one thing I'm not getting. If the studs are not threaded into the block, how does it hold the head down in this area? Just trying to understand how this works.

 

Scott
One thing Im wondering about . Since this stud goes down into the coolant passage , is it slowing down the flow of coolant at all ?

 

it is very open in the coolant passage in this area. would not pose a problem at all.

 

think of a hollow box. with pressure on the bottom of the box it will flex the bottom of the box. now add support in this box. now the pressure flexing the bottom of the box now has to flex the top of the box too in order to move it. it is just a simple support brace really.

 

Scott,
Thank you again for such a great product. I am going to have to order a set of these. I got your solid M/M , your wastegate relocations, and well your head package as well. Head hahaha Who doesn't like there head getting worked on.

thanks for repeat biz ryan!

 

you got MONEY My new engine should be done anyday now so talk about good timing.

Ryan

 

thanks ryan!

 

Oz, when are you going to start offering built motors with your headlift supporting mods?

 

i already am, lol. i have a couple qoutes to put together now, but wanted to get this stuff figured out first. all these mods will be standard build process for us, plus there is many other tricks i am not sharing here. this will be discussed with potential customers only.

 

How exactly does this work?
Here is a picture of the head where the stud is, and the second one is a picture of the block.So your mod runs a full length stud through the hole for the allen bolt, and into the head gasket that lays upon the surface where the two cylinder walls meet. wouldnt this in theory not only damage the head gasket in that area, but also PUSH the heads AWAY from the motor, when you want to hold them down??

 

The bolt doesnt go all the way through. Its just filling a hole to make the head stronger.

 

No, from what he said it sits upon the cylinder walls as a support for the heads.Unless I am missing something..Im confused

 

Seems to me it just fills the holes.

 

only if you torque the heck out of the bolt will you even be able to bow the bottom of the head, thus acting against the head studs. the bolt is not long enough to double nut it and it is only a slot for a screw driver in the top. i did it this way so people phyisically can't create enough torque on the bolt to do this. call it idiot proof, lol. now if someone was doing this mod during a motor build with 1/2" studs also, then a little more torque on it will make it even more effective.
again, the leaks have been on the opposite axises than the head studs, that is saying these areas are lifting from the block, this mod will strengthen one of those axises. there is no down side to it.

 

beat me to it. Is the nut reverse thread so the bolt wont back out?
