Ok guys, the pics showing the secondary ports....well the floor is not level, but I still think (after seeing the pics) that the ports aren't equal on size, at the intake manifold side.



I really want some opinions, criticism, suggestions\tips! This is my first time porting, by now you can tell I SUCK at arts (drawing), and my pulse is no better than a 60 years old man https://www.nopistons.com/forums/pub...O_DIR#>/11.gif



TIA!

You just gotta be careful you don't go too far down when you extend port the plates or the overlap will be very large.



Same goes for the exhaust ports when you do them, except don't go up by much and don't make them wider.



Have fun!

Thanks!



I am actually using the RB templates, wich are useless for the lower part of the port (on the rotor side\face). I mean, the secondaries goes deeper from the factory than the template, and on the primaries, the template just goes too low for IMHO!



More pics comin in this weekend https://www.nopistons.com/forums/pub...IR#>/bigok.gif https://www.nopistons.com/forums/pub...1047683329.gif

Nice job. The ports look big enough.

Can't really tell from the photos, but you haven't gone sideways much, have you? Gotta be careful of the outer oil ring and corner seal tracks... https://www.nopistons.com/forums/pub...#>/biggrin.png

Not really, except for the upper inside corner on the secondaries, where the bit grab a litle too much.... :(

Gotta learn sometime! I've done that too- that burr can kinda run away with you. Once I put a long gouge across the face of the plate when it skipped out of the port! Lucky it was an old junker plate https://www.nopistons.com/forums/pub...#>/biggrin.png



Pretty good for your first effort though https://www.nopistons.com/forums/pub...DIR#>/cool.png
