Farmall H puller build

Hey guys, I posted this on the Farmall forum and was sent over here. I've got an early H with a locked motor and I'd like to hot rod it a little while I'm in there. I pulled the head last night and it's currently got standard sleeves with some type of stepped piston. If it's possible to buy just one piston/sleeve I'll consider that route but otherwise I'm going through the whole thing. So, my questions are:
1. Does anyone sell a single sleeve/piston?
2. Can I build 175 c.i. with this block (or larger) and what does it take?
3. Has anyone here built an H for pulling and where did you source your parts?

Basically, I need all of the background information I can get.
 
This what I did with my H. I bored it out to take 3/&9/16ths in firecater pistons, did a cam grind, m carb, turned up the RPM's, a L P 300 head and a L P manifold. I am guessing I am pushing close to 60 H.P. with it. We do real well at the pulls we go to.
 
H blocks can go out to the 350 block specs.

Once the H block is bored 350 sleeves will go right in and still be as strong as stock, with rebuild options for the future.

350 firecrater pistons will hit the H heads.
You will need to cut the chamber a little bit to replicate the 300-350 chamber shape, or use a Super H thru 350 head and bolt it right on.

Thanks for the replies so far. Unless someone has a head they want to part with I'm stuck with the standard H head. In a nutshell what clearancing needs to be done to clear the 350 Firecrater pistons? Is it just a matter of mocking up the motor and massaging the chamber? What kind of compression ratio is normal with this setup?

Thanks
 
Hey N.D. Farmall H Puller! Would you mind letting me know how to get in touch with you? I have a few questions for you.
 
Chris I have a 300 head that will fit your H it already to go Port Polished little bigger valves and double sping if you want to really turn the rpm
I had this on my pulling tractor but found a Lp head to replace 952-913-0667 Bill
