351w heads D8OE vs. stock 5.0 heads?

[92SVOcoupe]

I have a set of 351w heads(D8OE) and i currently have on my car are the E7TE heads. Are the 351W heads a better head when ported over the stock heads ported? I am on a budget so aftermarket heads are out of the question. I'll be using a 306 short block(stock style pistons,forged) with a b-cam, ported cobra intake w/1" spacer, full exhaust, cai,75mm maf,65mm tb. , 155 lph pump and a 5 speed. Thanks!

E7TE that came on 87 or later 5.0 stangs are your best bet. The D8OE combustion chamber volume is larger than the E7 heads and will drop your compression ratio. i ported my e7s and i have a set of D8OE heads sitting in the garage...

Thanks for the info. My E7's are just gasket matched, i'm going to do some more work to them now. Thanks.

W heads were only decent until 73...
Early 76 if you don't mind all the emissions plumbing.

Those 78s (D8) are good for scrap iron.
