The answer seems pretty simple, you can either buy a 128 or a 113 head to replace with. Post on the parts section on here, I bet you get a response real quick..Now would be a good time to upgrade to a better set of heads..WW

Vortec heads are cheap then get a Vortec TPI base and SLP runners to compliment the new heads..

Then cam..then roller rockers.. then gear .. ETC...

Get another 113 head and port both heads. The 128 heads are a weak casting and prone to cracking.

Yep thats it. This car ran really well before too. My short block should be ready today,with dish pistons. So i am pretty much stuck with the 58 cc head. Going to have to make some calls today to find another 113 head.
