Edelbrock e street heads review. In this months editorial smitty tells us about the new edelbrock e street heads. I have been looking at the 75cc version e street heads 5090. What we did installed a fresh set of 23 degree edelbrock e 210 cylinder heads rpm air gap manifold and a complete moroso oiling system. Bottom line a sherman tank for the streets. I think the e street heads are basically regular performer heads but with a cheaper valvetrain. Thats fine if you dont plan to upgrade later on but it sounds like you may want to go bigger later on.
With aluminum heads you will be fine even at 110 to 1 because the aluminum dissipates heat much faster. E street cylinder heads feature as cast ports and are designed for entry level street performance applications operating in the idle to 5500 rpm range. The 906 heads on our 383 have a little bit of match porting and bowl work done but the e street heads provide better flow and an improved combustion chamber equaling enhanced performance right. I have iron 915 heads and im at 106 to 1 and use 93 octane and have used 87 accidentally without any detonation. However even at a total headintakevalvetrain package price of perhaps 200 more than the vortec iron heads the edelbrock e street heads seem to be the better.

First off you can get away with much more compression.
