I’m thinking either going to the 284hr or 290hr from the 270hr. I’m just worried about the amount of spring pressure for the screw in studs. The 284hr has the same amount of lift as the 270hr so I know that’s safe. The 290 is a little taller and if I calculated spring pressure correctly will bring me over 340lbs.

I would check out what your dynamic compression will be with the different cams. There is a calculator on here somewhere that a member posted. A lot will be dependent on what you run for pistons and what you end up with for combustion chamber size.

That is definitely part of my consideration. Ive played with that calculator a little. I’ve gotten a ton of photos of opened up CC’s so worst case I’ll do some grinding. But I’m definitely going to run flat top pistons.

Tore down the engine today to get ready for the new heads. Was disappointed to find dished pistons. But on the plus side I can run this cam for a year and upgrade next year.

Are those marked 60 over? That is a lot of bore for a Cleveland. I am running a small dish on mine and it seems to like it.

Yes it does. And yes the .060 does concern me a little. I’m going to pay attention to my coolant and start building a short block next winter. Run it as it is this year. With our conversations I’m going to go back with the 284hr since compression isn’t as much of an issue.

The good news on the old heads is it did have stainless one piece valves. The bad news was no bronze guides and this isn’t the only crack I’ve found.

New heads look awesome though. Can’t wait to get these bolted on.

Decided to grab the weiand intake I had bought in the summer for a coat of paint. Just need to decide if I’m willing to take apart the FiTech to paint it black or keep it silverish.
