As the heads will need harden exh. seats for unleaded gas.
Or do a complete rebuild.

Oh MY YES!!!
Only 26 thousand dollars
I can understand a professional race team having an engine like that but, it really doesn't make sense to build an engine with 500, 600 or greater horse power, especially if the vehicles primary (or only) use will be on the street/highway.
There aren't any Autobahns in the U.S. and the only place I know of you can legally drive 85 MPH, in the U.S., is on a 40 mile stretch of toll road between Austin and San Antonio, TX. (at least it was being proposed. Don't know if they've actually done it).
I understand the desire to build a powerful, high horse power engine. At one time, I wanted to build a turboed, fuel injected stroker engine for my '68 Mustang. But, some time has passed since that initial thought and the sensibilities kicked in to realize, other than a drag strip, there's nowhere I could (legally) use anywhere close to the potential output of an engine like that.
If I did utilize the full output potential of an engine like that on the street/highway, it would be under illegal circumstances and it wouldn't last for more than bursts of about a 15 to 30 seconds at a time. The rest of the time, all the money, time, effort and the speed parts themselves would just be a complete waste.
It didn't make good sense to me to spend several thousands of dollars on expensive speed parts, that for 99% (or more) of the time, would not even be operating in an RPM range that they were designed for.
The plan now is to take the H.O. 5.0L fuel injected engine, replace the stock E7TA heads with a pair of much better factory GT40P iron heads, install a slightly more aggressive than stock camshaft, install factory 24 lb/hr injectors, a 70mm throttle body, 73mm Mass Air meter, headers, dual exhaust and put it in the truck. This should be good for around 300+ horse power, get decent fuel mileage, have a good amount of acceleration and will propel the truck faster than the legal speed limit will allow. I have the engine and most of these parts and it won't be overly expensive to build and I won't be throwing tons of money on expensive speed parts that would largely never see their performance potential on a high horse power engine that would pretty much be completely useless.
I would rather spend that kind of money on installing A/C, redoing the interior, nice wheels/tires, etc. or, put it towards a paint job.
....as it currently stands, the worn out 240 in it now will propel my truck faster than the legal speed limit around here will allow.
I've been eyeballing this Snake instead of a F355. ...506 cubic inches and 510 HP, Oh, it has air conditioning too.
Anyone ever hear of the Silver State Classic? It's a bucket list item.
