Farmerhr........yep, 8-seals 'cuz there are 8-valves. They put 8-seals in the kit to make you ask questions. ONLY the 4-intake valves can suck oil. Seals prevent that. Otherwize you will complain about yer new engine smokey exhaust. HOT EXHAUST valves BLOW oil out their stems and seals won't prevent that. Throw away the other 4-seals. Simple, eh?
Surprizingly euff, being converted to 12-volts or having the weird 4-nipple frontmount dizzy has 'nuttin' to do with intake valve seals. .........respectfully, the smokeless Dell
