If you want to stay with iron heads, get the GT40's you already have ported. There is no out of the box iron head that I know of that would be worth the cost to buy if you already have GT40's IMO.

I find that hard to believe, comparing flow numbers of gt 40's vs company's like RHS, Dart, or even World Products, almost a 100 CFM at 500 lift, out of the box.

Basically would like to know if there would be piston to valve clearance issues if I used a 2.02 valve in a 64cc combustion chamber. If not I would try the new RHS's seem to be getting good reviews, at a not so bad price...

Every dart iron head I have ever seen run on a stock compression, long runner manifold, stock displacement, fuel injected Ford lost power compared to the GT-40 irons intil over 5000 rpm. They make great power up-top on a race car, but you've got to rev them high to make it worth it.

If I had the budget and it had to be iron, then I'd be looking for an old set of TFS high port irons, or the Ford Racing Sportsman head.


Ps. In this day and age I cant think of 1 good reason to pick an iron head over an aluminum head.

Take a look at the RHS cast iron heads.

If you have stock dished pistons, you want a smaller comb chamber to up the compression a little. Stock nominal is only 8.8, with Performers it's a calculated 9.0 and with mass air running a stock 5.0 HO auto ecu and larger mass air and injectors runs just fine on 87 octane with stock timing. And I don't know of any inline 2.02 valve heads that will clear those pistons. The twist wedge will and are a great upgrade for a street motor.

I was on a very tight budget and was going to use GT40's until I found a lo miles
pair of Ebrock Performer's with the 1.9 intake and 170 intake runners. Cleaned them
up a little and with an Explorer upper over a Ford GT40-351 port matched lower do a
fine job with a TF Stg 1, all budget items.

I think Summit racing has some inexpensive iron heads with 1.9 or 1.94 intakes - have been looking at them for a budget build for a real mild early vette top end upgrade. Their basic iron SBC heads are only $310 apiece with valves and springs.

Here's an older but very thorough head test on sbf's, and doesn't include the newer heads like the RHS etc, but can give you very good info on most of the popular heads that have been around awhile.

Any size valve will fit. It all depends on the cam you use. With AFR heads and a Trick Flow Stage 2 cam, I had to notch the pistons on my stock Lightning shortblock.

I'm just guessing here but he doesn't know a Lightning was made before 99.
