Will these 1.7 rockers fit on lt1 heads? I have the bigger studs.

Also if they do fit will My stock lt1 valve covers fit or will I need taller ones?

Here is the valve cover mod but I'd suspect youll need tall valve covers notched for alternator clearance or centerbolts and alternator relocation brackets.

So they will definitely bolt on lt heads then?

Do you have guideplates, hardened pushrods and the springs to handle them? I would honestly be afraid of the quality at that price. Valvetrain is not something to skimp on.

 

[924cgt]

Guideplates and valve springs yes. I am not sure what the pushrods are. They may be stock. The cam is a 503. I just want a little more lift.

1.7 rockers will not work well with a cc503. The ramp rate, or how fast the lifter travels up the lobe will be intensified on the spring side with a higher ratio. The XE lobe is already fairly fast for the normal springs used with them. It can lead to spring failure and valve float if the springs are not up to the task.

Those rockers you are looking at are scary for that price. A stainless steel rocker set is in the $450 range from Comp or Crower. I would recommend these as a nice budget rocker arm -- Made in the USA

The Comp Ultra Pro Mags are also very nice pieces for a bit more $..

Yes, stay away from the $100 stainless rockers unless you want to grenade your engine.

I've been running Ultra Pro Mags for a season now and have no complaints.

 

[cocobolo95]

yes comp cams ultra pro mags are great rockers. Unfortunately, 924cgt is looking at a set of ebay $100 stainless rockers.

I didn't want to put aluminum rockers in due to durability. I would feel extremely worried if I had "stainless" rockers, lol.
