Got the car running with the 24# injectors by gutting the stock fuel pressure regulator (and using an aftermarket AFPR), but now is throwing code 33. What did you guys do when installing a cam that causes low vacuum (or rockers)?

 

u ned to remove those 1.7's before u ruin the valve guides,il explain why after i eat dinner,but the geometry is really messed up,and ur gonan side load the valves really bad.

 

The Crane rockers were off to the side also.
Not overly concerned about the iron heads getting ruined, but please tell so others have a referance...

 

Problem solved! Guess the MAP sensor will read low vac when it's not connected, HAHA. 11:00PM and tired, I mistakenly hooked up the HVAC controls in place of the MAP (sofa king we todd did).

 

ok heres the deal with the 1.7 ford rockers,the distance from the stud to the valve stem center on a ford is further then a chevy,so when u use the ford rocker even though it physically fits it puts the rocker tip on the edge of the valve stem,as the valve is opening and closing most of the force from the rocker arm is pushing on the valve sideways,instead of striaght down the valve,which in turn forces the valve stem onto the side of the valve guide causing it to wear out prematurley.it will take some time to wear out the guide but it will eventually happen.

now if we can get the stud to vale measurement on the 60* head and compare that to the sbc heads,and its the same or dam close,those may possible be used without any worrys

 

SBC and 60* are the same, already found that out - but where to get cheap SBC high ratio rockers?!
