If it was me I would go with the 572-13 heads.I have found its best to go ahead and get the best you can at the start,because even if the 440-1 heads do what you want at the start you will soon be wishing you had gone with the 572-13 heads.I have never wish I had built a small engine.With the 572-13 heads you will also have enough heads to go with more cu in later if you should chose to do so.
I have been very Happy with my 572-13 heads,never once have wish I had gone with the 440-1's.

Just an observation on what each head you may consider will do. The 440-1, then 572-13, then B1, and finally the B1Mc.
The performance level goes up close to the same as you move up to each head. Although I think the 572-13 isn't too far behind the B1, The 440-1 will make about 850 on most builds, 572 another 50 hp, and so on. The B1mc has shown itself to make over 1050 with the right parts. So its a matter of cost Vs dollars, or if you really like on head style over the other, and you seem to want to stay with the Indys, fine. The 572 has different valve angles, 13 vs 15, and moved valve location which requires a different piston. I don't know if it is possible to cut the new notches in your old pistons, but may be worth investigating. The Rocker assembly's are different if you run Jesel. If the bars that bolt to the heads are the same, you may be able to purchase just part of the setup (exhaust rockers?) and save some $$.

Greg thanks i have spent a lot of money on my car and my motor and would like to freshen it up over the winter and get it to run at about tenth or a little more and keep the short block the same if i can but i don`t won`t to spend money on my heads if they won`t do it i could get a set of 345 cnc bare heads and put some of my stuff in them that`s what brad was talking to me about to save some money i just think 572s will make the power with a 572 cui motor because when it`s cool and the air good i can go 5.90s now but when the air is at about 3,400 to 4,400 ft and real hot and the track is slick i need about a tenth and i have had a lot of helpful talk

I am looking for a tenth or a little more the car will run 5.90s in good cool air but i need 6.00 to 6.02 in real bad hot air and a slick track it run 6.05 & 6.04 & 6.04 & 6.06 & 6.04 and i lost with a 6.04 and the air was hot and bad that`s why i was asking about the 572-13s .






It's your money..

So for about $1500 or so you can port the 440-1's and get what you need or spend $4000-5000 and get more than you need..


Chris..


Thanks Chris i pm the guy and will see what he thinks .
