Epoxy for portmatch CR head - Competition Diesel.Com

smoke machine · 05-17-2015, 09:33 PM

I have a big valve ported polished CR head that I have squired a single runner ZZfab intake for. I'm wanting to fill the dish between the flange where the intake will bolt and where the divers are so it'll be a true single runner for each cylinder. What epoxy is best? Pros and cons and so on

I was recommended Devcon titanium putty by my intake builder. I ended up using the cheap high heat JB Weld stuff because I could get it locally and I was in a rush to get it done. Seems to be holding up so far. I drilled a number of small shallow holes in my head to give it something to hold on too.

Goodson PRK-99 port reshaping kit. It's a two part epoxy, i used it on a couple heads to fill in the pockets between the runners and it worked well.

My engine builder said use Devcon Titanium epoxy also but finding a supplier was difficult in the time frame I was dealing with. I ended up using quicksteel epoxy. It was a two part epoxy rated for 500*. Make sure the package has at least a 500* max temp and the product is "machinable". It should say on the package.
