X-heads or J-heads on a 360 LA Engine

They aren't $50, far from it. The X-heads are stripped, no valves and no rocker assemblies. They're supposed to be unmolested, I haven't seen them in person yet. $400 for just the pair of heads.

The J-heads are actually one J-head and one U-head, both 915 castings. They came with the 360 core I bought for $300. One of those doesn't have any valves and neither has the rocker assemblies.

I'd like the 2.02 valves but it's probably not a necessity since racing is definitely not part of the plan. Just a fun street car is all I'm after. I really don't care about correctness, the car is not a resto car, it won't even really be a clone of a GTS or a 340 Swinger. It'll stay badged as a GT but the 318/904 auto/7.25 rear will all be replaced with a 360/A833 4 speed/8.75 sure grip. I can't afford a real 340 car these days and this is just to relive my youth a little and come close to a replacement for my first car ('69 Barracuda 340/4 speed). I bought that one in 1981 when I was 17 and like an idiot, I sold it. In those days they were easy to find and I didn't have storage to sit it in while I went to college.

I was going to talk to my local engine machine shop about 2.02's in the J-heads but I haven't done that yet and figured maybe some of the expense of that machining could be avoided with a decent builder set of X-heads. Maybe I'll just buy the X-heads and put them in my storage unit for a few years until I either luck into an actual 340 project or someone else wants them worse than I do.
I think I posted it but the fix if your 1.88s if they are sunk is to install 2.02s. i am going through it right now I have a set of Js with 1.88s in the machine shop. If the shop says they need it Ill have them punched for 2.02s out but if they don't Ill stay with 1.88s to keep cost down. I also have a set of x and js with 2.02s so I don't mind having a set of 1.88s. Plan is to get the 1.88s back see what they cost then put the 2.02 js in for work also. i do think in your situation, since you already have the heads, put them in the shop see what they say about 2.02s. I have noticed new 1.88 valves are affordable, while 2.02 new valves are pricey or unavailable. My machine shop guy said unless port work is done the 2.02s wont make a difference, and on the car noone will know just say it has 2.02s at the cruise night LOL!
