porting e6 heads??

[z2o_what]

i have a set of e6 heads lying around and i was wondering if they could be ported and "worked" to flow as good as e7s.


i wouldn't think they could be......but i figured that i would ask to see if anyone knows.

I've heard of some pretty amazing things being done with the e6 heads. I don't have any flow data on ported versions though. Most of the gains were the result of reshaping the cumbustion chambers and unshrouding the valves.

do you know where i could find any info on reshaping the cumbustion chambers and unshrouding the valves?

Your local machine shop would be a good source. You could also do a search for "e6 heads" in your internet search engine. I've come across various articles from time to time. I'll be looking into a little more myself here in the very near future as I plan to remove my heads and swap the stockers back in to prep these for a new combo. The headwork is not something that I could attempt on my own.

none of my local machine shops are doing any "custom" headwork other than 3-angle valve jobs, until thier work slows down


if i were to try unshrouding the intake valves myself.......and if i didn't do it properly would it make my car run worse than stock?........or would it have to be done professionally for the car to run right?


im rebuilding the motor right now......and a friend offered me a $150 and a set of "freshly worked" D80Es for the e7s i was previously running.
So im most likely going back to the e6s and i would like for the car to run pretty good.

theres not much you can do to harm an e6 head, they already suck
