Quote: Looks good...how many cubes...just a question..but is slimming down the space between the intake ports a bad place to gain cross sectional area by the pushrod pinch...I don't see any problem with a narrow gasket area between the ports due to compressive forces being greater on a smaller surface are...just thoughts????
Hope itydon't hurt..I worked mine down to about .080 wide but have not seen any degradation of the gasket with 22psi pushing on it.
There are a few tricks to get the air speed down at the pinch. Common wall is good, corner radius can be tighter than other parts of the port. Floor and roof are where you can really slow it down. It still ends up being fast, but if you don't probe the pinch area at the lifts you'll access, you may have a problem with flow at high lifts and also power loss at higher rpms. These were left somewhat fast because it won't be an all out race engine. Brian
