before my heads were untouched with a 226/226 cam, now my stock 317's are milled down .030 and i have a 228/232 cam? compression should of bumped up some with the heads being milled, but i still think it wont be enough for me to gain 4-5mph..... i'll be happy if it runs the same and not slower!!
yeah, skeet im pretty sure some cutouts will help out alot, a setup like yours needs to get rid of some air quick.... and you are right a very good night in the negative DA will also have to be achieved...

[QUOTE=litreddevil;4070384]it is fine just to get the most out of it a angle mill is better cause it till the cathedral in the port better and allow the air to flow better.a good set of ported 317 are around 800 to 1000 if you want more info i can get you in touch with the guy he has been doing it for a long time and has alot of dynoing and flow testing with ls motors.
