ferrea valvetrain

[greathuskie]

does anyone have any experience with them? im extremely interested in them, im building my head, and im the kind of guy who does it right the first time, when i put this head on i dont want to ever have to take it off....im also getting hks 264/272's to go with the valvetrain, but im not sure if i want to get this or the crower one which is considerably cheaper but not a dual valve spring

anyone got any useful info for me? please dont tell me to stay with stock or anything....

Both sets of valve springs made by Ferrea are too much spring for those HKS cams. Crower springs would be acceptable but still overkill, stock springs will work and actually apply more pressure than HKS springs, and the HKS springs are made to order for those cams. HKS springs are priced between the Crower and cheapest Ferrea springs or about the same as a new set of discounted stock springs.

Ferrea valves are nice but Crower valves are at the same quality level and cost $75 to $100 cheaper for the set. Just stay away from SI valves.

if i get HKS springs what retainers could i use?
