Thebacrew of my muffler on my engine are screwed up , they don't tight anymore. So if I order something like this could I just swap the head or is there a possibility it wont be the same fitting ? My engine is a zenoha and this pic is rovanScreenshot_20200104-184124_eBay.webp

ast time you said your engine was a rovan, now your saying it's zen, what is it really??? In the case if it's actually a zen, don't, those China special kits are trash,just buy a replacement cylinder. If it's a rovan, don't, just buy a zen ?
Pretty sure, you can also helicoil the threads

Lastvtime I did a mistake it's written on it zenoah. I'm just not 100% sure if its 30.5 or 32cc tryingbto local it but having a hard time
What is helicoil ?? Like make th bigger ?? If so the previous owner already didvthat
 
I don't know if you have any friends who are mechanics but if you do I would Time-
Sert it.Helicoils are good if done right but they don't hold a candle to aTime-Sert.Time-Serts are the preferred repair on automotive forced induction repair for stripped head bolts.I would think for these little engines the helicoil would work perfectly but that all depends on the previous repair.
 
A time sert or lock n stitch repair would be a waste in this application. The helicoil would work just fine. The cost of the inserts alone would make a new head look cheap. Let alone buying the tooling to install them.
