4age bigport head: port & polish

[Os7213]

Hey thank! Firehawk
I have order today the Levin\Trueno bible cause like i can see these infos are very useful since they give the valve angle grinding and ect...!
So i think ill be able to build up the motor with the N2 blueprinting spec.
I just hope they give infos about clerance\tolerance for all parts of the engine! My setup for now is this one 4agze smallport head+black-top block and i hope matching this with the N2 specs.

Thank for the infos about the clay! I think ill be able to build the head with no problem So the clerance of the piston to the head 0.050in -0\+0.030 but be as close as possible to 0.050in with squish area machined.

So firehawk tell the N2 spec 4age use a 1.1mm(0.028in) gasket compressed. So we have 0.022in to play for the piston top-dead center and the squish area. So if the piston is at 0.015in of the top of the block we have a squish area of 0.007in who give 0.050in clearance but im sure we can add almost a +0.002in tolerance without problems! Hope my math are okay this is just for exemple! But hope im in the right way!

Just for info someone have found something about all the specs for the 4age 20v black-top? Or even a manual for ae111? Cause im looking since many weeks now for anything about specs\tolerance\clerance of this motor but only thing i can find is about crankshaft compared to other 4age...but nothing about tolerance\clerance!

Thank a lot guys
