4age bigport head: port & polish

[Os7213]

Nice no problem with time that happen really often in forums thank a lot for the answer!
I now understand why u keep chamber size intact and just doing squish area.
Oh! im not sure if you have read the entire post but do you think i going in a right way to calculate the squish area depth?

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!

Or you have your own techniques to calculate the area depth? Im really interessted to learn more about 4age porting and head configuration and your help is very appreciated thank you all! And sorry sometimes for my bad english Oh i almost forgot i have few questions and drawing about port configurations if you guys are interrested in talking about it let me know.
