Started taking the car apart at 1 pm had the top end off by 4 and dropped them off at the head man who is 4 miles away .Already got them back at 6 and will put it back together tomorrow . The valve seal were not allowing enough oil to the stem so we put some old style seals in .He has seen this happen before on exhaust valves . Hopefully running by Tuesday night and racing this weekend .
had many 428 CJ and SCJ cars over the last 30 years.I currently own a 68 1/2 coupe and a 69 R code SCJ Coupe and a 70 R code SCJ Cougar Eliminator .I am looking for a 70 428 coupe if anybody knows of one for sale.

So you switched from ' perfect circle ' types to umbrlla's ?  New one on me.  Haven't heard of not enough oil on the stem's before.  Oh well your back at it in record time.  Be sure to post how your doing ?  Brian

Just on the exhaust valves he has seen similar things happen before with exhaust valves on other heads. The stuck valve barely touched the piston at all just knocked a bit of carbon off of each .So that bullet was dodged .Only really out intake and valve cover gaskets .Have Cometic reusable head gaskets so some gaskets the $20 the head man charged me and time for my helper .I wouldn't dare pull a head with exhaust manifold attached by myself to awkward and heavy.

Its running again put the heads and manifolds and exhaust hooked up on Monday and finished the rest tonight .It fired up instantly and runs well lots of oil pressure and ran it till the temp hit 150 . Ready for the NMCA race this weekend in Indy .
