I got the 355 crammed in the TA today, and when I attempted to put the valve covers on they wouldn't sit down. I swore I thought I test fit them, but evidently not. What valve covers can be used with the GMPP 1.6 RRs? I'm considereing LT4. Also, Jeg's sells a set of Moroso's that are centerbolt and supposedly machined for more rocker arm clearance. What valve covers has everyone else had success with? Thanx.

 

BTW, this is fairly urgent. I need to order the valve covers tomorrow.

 

ttt for ya.

 

My stock LT1 valve covers worked fine with the GM 1.6 rr's. I didn't know that they wouldn't fit LT4 heads. I would get the LT4 valve covers though. I've been wanting to get a set of them, they look sweet plus they quiet down the noise from the valvetrain.

 

Summit makes a centerbolt valve cover that is taller and it looks pretty sweet. Here's a link:

That's what I'm going to be putting on my car. If you don't like those, just shop around Summit for centerbolts.

 

Those Summit one look awsome but 2 bills is alot of $$, then you gotta beat 'em to fit the alternator. How much are the LT4's.

 

With all hardware, the LT4s are now ~$180.

 

I have LT4 heads with GMPP RR's and had no problem clearing the rockers with my stock LT1 VC's. I since switched over to a polished alumnium set from Racenet, which gave me more clearance and were already fit for the alternator (they're super-sweet BTW). They were backstocked and took a while to get here, though.
