Ok i see :-) yes its a euro motor.. what is the best way to check this clearance? I've read about a method where they use clay. What is the minimum clearance that you need to have to be safe?
Is it a good idea to fit this kind of cam on a stock m20? Any gains? Or should i save me the trouble and just fit the original cam?

Yes, especially with a high-lift cam and what I'm assuming is a higher comp. euro "i" engine.
And anyone doing a proper stroker would not be decking the head/block unless absolutely necessary (and in those cases a new block/head is preferable). Decking the block/head for the sole purpose of gaining compression is a short cut indicating a hack-job build ethos.Leave a comment:

Even if the block or head are not going to be decked? Just a light resurface of the head.. I'm thinking this is more a problem with stroker motors where they take more material off for upping the compression?Leave a comment:

Regardless of what is said, you need to do a manual piston/valve clearance check as a part of your reassembly. CANNOT stress this enough.
Just had a customer in New Zealand this week who blew a brand new 8k race engine because the machine shop took more off the head than they said they did.Leave a comment:

cam question
hello!
i'm currently rebuilding the cil head of my m20b25. valve seats, valve refacing, valve guids, valve seals, new valvesprings, new rockerarms. Now i'm thinking about putting in a new catcams 285/285. does anybody has experience with this cam? I've read a lot about schrick 288 and that some people love it in a stock m20b25 and other say it's a waist of money and that it's to agressive.
what about piston to valve clearance?
this is info about the cam: http://www.catcams.co.uk/acatalog/1300525.pdf
tnx
