Domed pistons

With factory heads what compression ration would these get me up to. I have access to AV gas but I'd like to be able to run 93 if possible.

The engine is a 76 318.

Appreciate the info guys. I wasn't expecting an exact number just a ball park figure. The reason I'm looking at buying these is so I can avoid having to ship the block and or heads to a machine shop to be decked. I don't have one ine local, and I assumed it would be cheaper to use these pistons then to try and find and use a machine shop I have no history with.

The motor is a 76 318 out of a M880 has been rebuilt within 2 years of me getting it. Crank has been turned and its been bored .020 over. Has summit brand headers has a stealth intake 650 eldelbrock and summit .441/.441 .218/.228 cam.....I'm wanting to step up and use a howards .510/.510 .247/.247 cam

I was looking for a set of 360 but everyone around where I'm at thinks there gold. For the price of them and then having them gone through and cleaned up I could buy a set of performer RPM heads. But since I can't swing that I just did a home port job followed 1 of the threads on here actually. And for valve spring I ordered
Howards Cams 98438-K34. Will I need to get the spring seat machined for these and If so is it possible to do myself?

Hang on a sec; is that [email protected]?
With stock 1976 iron heads?
Back up the bus; what are you trying to achieve? and what will this engine be going into?
It seems to me, on your budget, you are headed for disappointment.
