Well, I got my heads a few weeks ago, they are KAUFFMAN D-ports, not Edelbrock D-ports, not sure why I thought that, must have been confused during the conversation, when ordering. I have them at my machine shop, so my machinist guy can bash on them, he is super picky, and builds a lot of high RPM racing stuff that wins a LOT, so I can listen to his bitching. He keeps telling me I don't want over 9.25 to 1, the stroker kit/head combo is designed for 10-1 or 10.3 to 1, Kauffman didn't have larger than 85cc chambered heads, so we may be putting thick gaskets, and or leaving the deck height as high as we can.
My Machinist guy says with CA's piss gas (max 91 octane) I really don't want over 9.25-1, or I will have to mix in race gas, and/or have no timing advance.
Any thoughts on this? the gas here does suck for high compression.
