I also posted this in Banter and Chat......(Just so you don't have to let me know I repeated...hehehe)
okay in the how to modify..... book it says that when porting you need to get all the ports the same size...Now i should be able to get them very close but does it really have to be exact when the stock version has so much varience?? Like the average difference is around .020 or more...
Also in the valve area on the head the combustion chambers are all different to...some have ridges and some dont they just don't look uniform...now should I go ahead and smooth these areas out and go for more of a well rounded dome? and should I enlarge it to the area that matches up with the opening of the head gasket? ( I have a carbon ring on the flat part of the head larger than the combustion chamber of the head...ya know what I mean??)
I am pretty confident from what I have done so far that I can get some pretty precise ports and all but what will happen if I don't get them exact? Is it safe too assume that is is safe since original was not perfect?
If anyone else has done their own heads and you have any picts. or pointers please let me know...
Thanks all....more to come probably!!!
Z ya later
