Thank you Zen Mod for your quick answer.Was just preparing to drill another hole 
I have at hand some kapton tape but is sticky at one side and I`ll want to use this with thermal grease between heatsink - tape and tape - mosfet.From what I read Kerafol Keratherm is better than mica(kapton) but I`ll have to do another order and wait at least 2-3 weeks and to be sincere I am fed up waiting and my budget is pretty limited.
So what do you suggest?(you already did but...not in this situation meaning my budget limitation and time)

+ if you are concerned about thermal resistance, grind the anodising off where you mount the output devices (and/or polish the blank surface right before you mount the insulator/device).
For changing the bias, the whole idea of this DIY endeavour is to get a grasp of what you're doing.
Early on in this thread it has been mentioned (4-eyes, as usual) that the 68Ksomething can be replaced by a lower value and a trimpot to fiddle.

With R27 stock value (68k), bias is about 1.2A per leg.
The smaller R27 the lower the bias.
I did a search for the words on google and the returns were : now I am a real First Watt guy...... - diyAudio and Pictures of your diy Pass amplifier - Page 3 - diyAudio
at which of these do you refer? can you please give me a direct link?
Thank you
Pfff, tiresome.
