The intake rocker arm bolts protrude over 1/4" through the roof of the AFR intake ports. This has to cause some unwanted turbulence that could be mostly eliminated by removing that much of the bolt end.
Anyone have info on whether this is a worth while mod.

 

The AFR's are debateably the best head out there, so why screw with em. Everyone with ported heads has this same issue.

 

all ported heads have the rocker bolt protrusion, air flow restriction is minimal.

 

I'm not after the last drop of performance so I it let go. It is the un-threaded extension of the rocker bolt and would be a easy fix. I'm going to replace the bolts as when I torqued them to 22 ft lbs, I didn't like the way they felt. I have the PRC gold springs and they will stress those bolts more then stock springs. I think I'll wack the replacements. I hope ARP has them.

 

....EVERY ported head I have seen has the rocker bolt protrusion removed.........thats a standard thing to get out of the way.....

 

i was refering too the rocker bolt being the protrusion

 

OHHHHHHH......my bad........if the bolt is that long it should be cut off

I still think your "got search button" smilie is the best.......it needs to be in the smilie list......
