I have a set of E7 heads ported and milled 0.030 they have crane dual valve springs and they have 750 miles on them, all work down by a machine shop in middletown ny, comes with painted valve covers
It won't lower compression it will bring it up and it brought my compression to 175 in each cyclinder and I will have to get back to you on the shipping

Sorry I ment raise$. You dont know the ratio then. Were you running 87 octane or will it have to run higher octane fuel? Do you have better pics of the porting?
I used 93 gas but I'm sure if u have to...depends on your set up what are you planning on running?and as for pics I will get them later for you I'm at work texting this off my cell phone
also how much HP gain did u get with these? im running stock e7s with a latter cam, edlebrock intake, 600 carb, and full exhaust. i know my heads are very restrictive so im wondering how much these will gain.
I ported and polished a set of E7's for my '86 and saw a huge difference. While the '86 head was a weaker design, the E7's took off about 5 tenths in the quarter mile for me.
