I was under the understanding that the F7R had valve guides and the F7P didnt, not that the valves were bigger
valves are bigger on willy , head differs slightly both engines have V.guides
fpmsl @ some of these replies.
16V doesn't have valve guides good one, lol
Bottom end has different stroke, bore and block casting.
To make the 2l rods clear the block on a 1.8 you need to grind the block and depending on the casting sometimes make a big hole sothe crank can turn in the block.
Thats why the williy stater is the same size as the 1.2/1.4 starters as the fat 1.8 doesn't easily clerr the ribs.
