RHS heads are prty good too. there mid flow numbers are great and thats wat u want think they might b a lil btr or less then trick flows but there cheaper and you can mill them to 37cc huge thickness very strong. i would say its one of the best heads if not the best head out thr for the money. you can take the 500 bucks you save and by smthing to make even more power.

With a MS4 the PRC heads can be setup about 60cc chambers & still clear p/v for the MS4. They will also include a good spring kit so you dont have to upgrade.
With the TFS heads you'll need a spring upgrade to run that lift & best case you can mill them to about 63-64cc.

I bought the 220's and got the yella terra for less than the 215s and still made great power!

dude go to your local speed shop or order these ford racing shims from jegs M-6529-A302. they work perfect and fit perfect...check out my thread hear.

all you need to get the tfs heads to work is .090 worth of shims under the stock rockers to correct geometry and in turn you need to measure for a longer pushrod. weather you go with a thicker pushrod is up to you. again check the thread and see how i did it. also get the trunion upgrade while you at it...not that hard to do with a vice and time time
