Just curious about whether or not a set of Dart Iron Eagle 2.05int 1.6ex 215cc runners would fit on an otherwise stock 327-210 HP motor. I thought that maybe with valves that big there might be some problems with them actually getting too close to the cylinder walls. Is this a problem or just a rumor? Also what would this do to my performance? Thanks a bunch!

Yes, they will physically fit, but expect your throttle response to vanish. Way, way too big of a port for a street 327...the 180cc's would be a way better choice. The 215's are more suited to 383's and larger engines.

Heck, the little motor only needs a 170cc head on it along with medium valves unless you want to step it up later!! Then add the big valves!!

Good old-fashioned double humpers or a set of W/P's SR big valve torquer heads would be great...

Try to shoot for 9.75 to 1 CR. so you can run pump gas..... May have to use the .015" or .022" shims to get there as well as 67 cc chambers???

Add a 268/218 hy- cam or a 270 to 280/230 solid and be really good to go..

Oh, almost forgot the 600 Holley, Performer or 8004 intake and adapter and cheap four tube, long headers...

Yes, what he said. Way too much head for a stock (or even heavily modified) 327. We run some Pro Topline 200cc heads on a friend's worked 327 and even they are a bit too big.

You guys got a point. I did forget to mention though that these heads eventually (near future) will go on the 350 I'm building up. So in other words, I want whatever heads I get to work best on the 350 but they also need to at least work on the 327 until then, just a couple of months. My 1.74's are shot is the reason. So would the 200cc 2.02 version of the Dart heads work best on the 350? Thanks guys I know I'm being a pain.

That's exactly why we put the 200cc Pro Toplines on my friend's 327. I will be building a 383 for him this winter. If you eventually will put them on a 350 either 180cc or 200cc head should work well.

If the RPMs will be lower and it'll be more of a street combo then 180cc heads would work well; if its a max performance street/strip type combo you might get a little more out of it with the 200cc's (of course you'll need more compression and more cam to take advantage of the bigger heads).

It depends on the brand and flow characteristics etc, too. My suggestion would be the ProTopline 180cc heads. They should work well on your 327 and on a 350. The ProTopline 180's flow as good or better than the Dart Iron Eagle 200's if I recall. There are some other very good heads out there (like the AFR 180's) and Trick Flow 195's but you can't beat ProTopline's prices - they are good quality too.
