I would advise to decrease the combustion chamber size to increase the comp for that 5005 cam.
It's a heavy bike so the higher comp will help the cam to come on a little sooner. And if he does shave the heads then he'll need adjustable pr's...

He is dead set on using the factory solid pushrods in his bike. He says he had one come lose years ago.
I believe hes going to get a set of the SE heads and keep the original heads in storage for later use.
Im thinking the factory pushrods arent going to work with the SE heads and EVL5005. He says theyll work .I say they wont work. Whos right?
They will work but will be noisy.. Stock base circle is .530 and the 5005 base circle is .515 so he will loose that much on the stock preload of .100" which will put him at .085" preload. With that said it will be noisy especially because of the lift and faster ramping.. Will definitely need spring as well to accommodate.

I agree. Even with SE heads, which are getting scarce for the ones used without special pistons, out of the box they were only good up to about .525 lift and with that much cam, some things are going to have to be re-worked. Special or custom made solid push rods are the only thing that will work in the desired recipe.

The customer is always right - until they aren't... then they usually blame it on the shop.
Thanks everyone .customer is always right. Ive got to remain friends .
Theres plenty of time before the upgrades hes wanting. Weve got to take care of the repairs and cleaning first.
Hopefully in the meantime, hell come to his senses about things. He might change his mind half a dozen times before its put back together again. I dont know if hell even find SE heads for a price hes willing to shell out.
Me personally .Ive never had any issue with adjustable push rods.

Neither have I... set right it shouldn't be an issue...
Easy enough to use solid pushrods, just use adjustables first, adjust to the correct length, measure. Send the dimensions of the pushrods you need to Smith Brothers and they will custom make the one piece pushrods.
I`m also a fan of one piece pushrods. I had two adjustables come loose on my Evo, the first time no damage just a lot of clatter, the second time it cost me a lifter.
