I seem to recall that your 347 is a street/strip motor....
The 185s would get my vote.
Great head.
The 205cc heads would probably hurt low end and midrange.
Alex can sell you a set also.....

I've got AFR 185s on the 342" (5.0 based) stroker in the Fastback. The car is set up for the street, basically concours with bolt-on performance parts. Traction bars are the only drag-racing specific part. The engine seems very powerful with little traction in the lower gears (toploader) and lots of top end. A trip to the track produced 111 mph at 13.2 on street radial tires and no special tuning. The 185s would seem like a good match for your 347. ------------------

The 205 would be a great head as long as you plan on running it from 3000-8000 rpms all the time with large open exhaust. Otherwise the 185 should provide plenty of flow to 7000 rpms.  ------------------

On the AFR 185's how much lift will the valve springs hold up to. I am looking at getting some for the 65 just wandering if the .592 lift on my cam would be to much for them. Also would I have valve to piston clearence problems with the 12.5:1 pop ups on the 185's?------------------

Don't know about the pop-ups, but I know that they come with choice of 58cc or 61cc chambers and the stock springs are good for up to .550 lift roller cam. They do offer an upgrade spring for larger cams.------------------
