My car is going to run on 89 and I used 87 before, but I still have like 3-5 gallons left in the tank. How would i go about Removing it?
(87+91)/2=89all we have is 91 should I put that in there? with like a octane booster?
tHERE IS NO DIFFERANCE BETWEEN 87 AND 89 OCTANE.
welll dcg33 uses 89 with no problems soo ya... Thats what I will be using becasue the closed chambered heads letyou use lower octane

thats also with a .040 quench,did you quench your motor? if not you,ll need the 91
.040 quench? He said he used the fel pro head gaskets with 0 deck pistons and magnum heads. Thats what I have
As long as your pistons truly sit at zero deck and the compressed thickness of the gasket is .040, and your heads cc at the same size as Daves, then they should both react the same to the same fuel.
