I am rebuilding a 84 200x. Machine shop has reworked the heads( 2 angle valve job, springs, valve seals). Bored .040 inches over using a wiseco 10:1 comression piston. Dg headpipe and muffler. Needing jetting recommendations on this set-up if possible. Thanks jd

 

There's no way to jet that over the internet too many variables. I would start 10 up from stock do a plug chop and go from there. P.S. welcome to the forum
