Teapot cylinder head interchangeability

[Forced2]

Hello! New here. I've searched through the forums for my answer and was not able to find much. Lost a valve seat on a teapot 750 dot head. I can not find another dot head, but I have found several 1100 heads. Can anyone tell me if any of the 1100 heads from the short stroke engines will work. I know they will bolt on but will the combustion chamber diameter work with the 750 bore. Also will valves clear cylinder bore.  I should also add this is a built engine with custom rods and pistons at 7.5:1 compression. It has been bored to 76mm. Running welded and reground cams. with blow through turbo setup. valve clearance to pistons may not be an issue. If anyone knows the fitment for a stock engine i can go from there. Thanks

Hi and welcome to OSS.

An introduction is always nice, no wait.

It is mandatory.

Hi mate. Welcome to the club! Have a look at ‘Frankensteins Pages’ in The Vault.

If your running a DOT head than you will lose compression even more by going to a 1100 head. The DOT head standard is @20cc the 1100 depending on type can be @26cc

All 748, 1052, 1127, 1157cc cylinder heads are interchangeable. But you need to do your own engine mathematicals.

Awesome! Thank you.
