hello.
solid tappets are a drop in with the correct push rods and many advise the change to solid .

with much reserch you will find web cams and lifters the prefered choice by most.

of course you can double thrust the camshaft two ways only to do thiat buy two sets of bearings or go to vw with a part number of the thrust bearing only. you wont find them listed as a kit anywhere as far as i know.

buy a new cam wheel or have the old one of the stock cam spot faced around the rivet holes so bolt heads dont sit proud .

if as i suspect this is a cu case you will only have 1 oil releif up by where the oil filter goes.

good luck.
