Replacement cylinder head for Predator 420cc Hemi needed

thatoneguywhodoesthings · 04-01-2018, 02:20 PM

Thread bore on my 420cc Predator Hemi cracked on the outer (right) side, so I cant secure the exhaust header to it. I've seen plenty of replacement cylinder heads online, for the previous models but none for the hemi. Anyone have any suggestions where I can find a replacement head?

I don't know where you get parts for them other than predator (HF) if you can, but they might be out there. Try searching 4cycle.com for info they mod them. Or as I posted on your other thread find someone that can weld alum.

Thanks. Very few aftermarket parts for the 420cc hemi right now, mostly only for the 212cc. I'll look into the welding part, the problem is the thread bores look like they are stripped too so they would have to be re-threaded with a tap and die.

Sho, I might just get another engine and keep it for parts. Its a small price to pay since my pops is 70 and just wants this thing to run right now. He definitely doesn't feel like spending time working on it.
