What about all that procomp stuff on ebay? like stainless rockers and what not...that stuff worth a crap or no?

I bought a set of stainless 1.6's just to have them on hand. they in no way compare to comp cams or crower. In fact the front rollers have .002/003 clearance on the pin. They would probably be o'k for a flat tappet spring with maybe 135/140 seat pressuse but after looking at these i wouldn't put on a set of PSI's valve springs with a 260lbs seat pressuse on them. I just wouldn't trust them that far.

Zip.

You have to be very careful buying some of that really cheaply priced chinese parts. Some of it is absolute garbage, some of it, is actualy pretty decent. Buyer beware. Personaly, anything to do with valve train, I would stay away from. That has to be the biggest cause of engine damage/failures there is. When a rocker arm is described as follows, "Excellent for budget, low lift applications. Needs good oil supply and low spring pressure to survive. ". That is an actual description of a set of roller rocker arms. Yah, that wording sure instills confidence in my mind.
