Now doing research on my roller rockers, leaning towards Yella Tera because I've used them in the past. They are on my current engine. But the question is - 1.7 ratio or 1.8????

Yella Terra are what I’m running on The Beast. I really like them, nice product. Roger Vinci had a hand in their design, not sure if you knew.Now doing research on my roller rockers, leaning towards Yella Tera because I've used them in the past. They are on my current engine.

I was not aware that Roger had a hand in the design. However, I too have a set in my current engine. In discussion with him right now via email on recommendation between the 1.7 or 1.8 rocker ratio rockers.Yella Terra are what I’m running on The Beast. I really like them, nice product.

You should be fine with the 1.7s unless you're running a high lift cam and will also be running high lift springsIn discussion with him right now via email on recommendation between the 1.7 or 1.8 rocker ratio rockers.
I do appreciate the comment though - I kept second guessing myself.You should be fine with the 1.7s unless you're running a high lift cam and will also be running high lift springs
Edit: 30min too late on this one lol
dumb questions are better than blowing up a new motorI do appreciate the comment though - I kept second guessing myself.

Well, with me it might take more than just a few times....dumb questions are better than blowing up a new motor
i guess i dont mean dumb questions, more of making sure you completely understand something even if it takes a few times lol
Happy Birthday to this beautiful girl who has brought so much joy and happiness to our family. Quite frankly has taught me how to stay young at heart - even after 15 years she is such a puppy. Our appointment was all very good news. Although she has a mild case of degenerative valve disease she received a positive diagnosis - no Medication, no restriction to diet, and no restrictions to all activities. Blood pressure was normal, breathing rate was normal and heart size and chambers all look great. She is just getting old like all of us.Yesterday we took Molly (she will be 15 in May) to the vet for a routine examination and her 3 year rabies shot. During the exam, the vet identified a heart murmur (rated 3 out 6 severity).

Talking to her and possible options - her recommendation was for her to see a cardiologist to determine exact cause and health of the heart. My first response was that she was approaching 15 and I was not sure if I wanted to spend that kind of money. Looked down and Molly was looking directly at me with her puppy eyes. Yes, she may be going on 15, but she still acts like a puppy. So, I scheduled an appointment with a cardiologist May 23rd to discuss options.
So, reading through my last several threads I was not clear on the compressed thickness of the head gaskets I will be using. When I ordered my heads I was talking to a senior tech at Summit Racing and he said based on what I was building and the information I gave him that the 0.055 gaskets would be great for my build. Turns out I think his suggestion is perfect for me.
Thanks for your great insights and recommendations throughout this build. I don't have the exact numbers with me at the moment. But I did work with both Texas Speed and Summit Racing, providing both companies with my measurements. I do remember there was negligible difference between the corners and the middle cylinders. Only surface prepping was conducted on the block. With the style of pistons I'm using and the heads I picked along with the other measurements - it was essentially a compromise between compression ratio and quench. Both gave me ranges of head gasket to use with Summit Racing recommending a slight thicker gasket. Texas Speed provided me the rotating assembly and was confident this combination would be great for what I was trying to achieve. Deck height, measured at the crown (lowest point on piston) was .006 below the surface Shown earlier in this thread). However, the piston has a raised section (can't remember that exact number, in my notes I don't have with me) that extends into the chamber of the head. Black Bear Performance has my information and will be giving their assessment too. Quench is a little higher than I would like. Still weighing options and determine whether I will do something about it.This geek wants to know- You said it should yield 11:1 SCR (which is great). But, what are the other details such as piston volume? I'm curious of the quench height and if you measured all eight pistons. In factory form, they come out of the hole around .008" to .012", and often around that range on the same block with the corner cylinders having the largest differences.
.055" gaskets are slightly thicker than OEM. Factoring that the block has been decked (but minimally as a clean-up?) and the heads likely have less meat on them than factory heads, I'm assuming the pistons are factory spec. I'm sure you've covered all of this already but it's been a while.
