Make a bushing the size of the head stud hole with clearance for the stud in the hole, than install with sealant, stops any possible transfer of coolant. Bushed holes should have sealant on the head stud instead of arp lube

There shouldn’t be coolant anywhere near the head studs in an rb engine

Block didn’t take long to get built and shipped. It landed this past Friday at the shop. It was a smooth and easy business transaction with the shop in Canada. Also the Unigroup camshafts came in. Got them fitted up and ready to send the head off to get cleaned and the New valves (guides and seals) installed. More to come.... 

[Dewayne2121]

Not sure if I’ll be able to get the head Into the shop before Christmas but the cams are fitted and ready for the rest of the beadwork!

[Dewayne2121]

The head came back and now it’s time to set up the valve train 

[Dewayne2121]

Just more eye candy for the meantime...

A little more progression photos:  

 

had to order 28 shims from SuperTech to get to this point. But finally both intake and exhaust completely done. Waiting on the head gasket now. (It’s enroute). It’s a tight fit!

[Dewayne2121]

Long overdue but the journey has come to a beautiful moment. Motor back in and back on the dyno

I originally was shooting for 450 to the wheels and met that goal and some thanks to E85 😈. Low boost 15 PSI 513WHP and 357 TQ. Due to stock tranny high boost is stopping at 20Psi and 569WHP 396 ft lb TQ. I’m very happy with these numbers and cannot wait to learn this new beast.

Don't do this unless it never gets hot where you are.

I'm guessing there is data stating these are not good in hotter climates??

[r32-25t]

There’s plenty of people who have had over heating issues as soon as they fit them
