what kind of gains can i expect from the gmpp head and how hard of an install would it be

 

I believe the head is a L61 head... Install would be very time consuming, but not too hard. Keep in mind though, I believe the head is ported to fit oversized valves, so you will need to purchase new valves as well. While your at it you should really just upgrade the whole head. Its just one component in the whole process

 

Uh what? This is the LSJ forum right?

Again, like I said on RLF, its an exhaust ported LSJ head with full stock valvetrain including cams. It's not hard, just time consuming, and if you are planning on upgrading cams, upgrade the springs, seats and retainers.

 

....what are you talking about?

hes referring to this head:

as in, valvetrain not included... note the L61 only as well.

what head did you think he was talking about?

 

Probably XGH734, the GM-R LSJ head.

 

do they have any specs on the porting done on the aftermarket lsj head for sale on that website?

 

that ******* hard to find?

its only for 2.2 right? i mean theres aftermarket co. but not gm?

im not sure?

 

Nope, this one is only for the LSJ
