Have 98 A4 with 226/585/112 Cam Need to know if Milled .03 Heads will be a problem AS FAR AS CLEARANCE ISSUES ? Any help appreciated. Purchasing heads tonight need to know.

 

if u still running the 98 engine then u should know that ur heads bolts r different than the 99+ ... they r perimeter bolts , 99+ have a center bolt type , check jrp`s super FAQ for the pix and the differences ,

dont worry u can fit the center-bolt type heads , u need to change the valve cover and some other NO BIG DEAL things ,

this is all what i know ,

 

should always confirm p/v with clay, only way to be sure. are they stock diameter 2.00 intakes?

 

These are off a 98 So they will fit no problem. I am just wondering with the cam I have and them beingmilled will I have clearance issues. Yes they are stock valves, Ported Polished Milled .03

 

u need valve cover ( get them from a salvage yard ) and coil pack brackets that mount on top of the center bolt style covers.

as long as i know these r the things u need if u r using a perimeter type bolts and u want to go with a center bolt type heads .

maybe u need to flycut the pistons maybe not .. how would u know ? as smask04C5 said u need to confirm piston to valve clearance using the clay method .
