ok guys i have a 2001 gtp with burnt valves going to have to have a valve job.:th_depressed: also going to get ported manifoulds and ported supercharger done to at same time:th_thumbsup-wink:

my problem is im looking into zzp or wbody both sell Si stainless valves for the gtp. showed i run stock sizes. Or showed i have the heads ported to go up one size bigger valves.:confused:

rest of the valvetrain will be comp cam rollers, retainers, and rods.

im also looking at 90lb's springs will they work with stock rockers and stock cams???:confused: hard yes and no:confused:
 


Get valves from intense...manleys...I did.

If the heads are off and you have the money...get them ported and polished. Comp Cams rollers? If you have stock rockers and a stock cam you dont need stronger valve springs.
 
i dont think there is a point in droping the money for the valve if its still on the stock cam and rockers. invest that money in a cam or something.
 
Intense for valves as blue said

And if your willing to pay get your heads ported and polished I have mine apart right now and the valveseats on the exhaust were hammered to crap and needed to be replaced

Might as well cam it while its apart ;-)
 
dont buy new valves unless you go bigger. if you go bigger then get manley valves. if you go bigger you might as well port the heads and get a cam.
 


Found out it it’s not my valves. Got really lucky. Guy did a compression check again from other shop that knows more. said not valves have a ring that’s by passing but he said its nothing really to worry about do to how well modern rings are made will still last me 100,000+ of hard use if running good in oil changed on time.
Found out my big problem is my 4clyender is not getting enough fuel. Might be just a cracked intake gasket and a bad injectors going! do to I got fuel on top of block.

What are strong intake gaskets?

Also what injectors showed I get?? I’m looking at zzp remand and flow benched 33lb ones.
 
Don't you have a GTP already? Why do you need new flow matched injectors? If you need injectors I have a set of #33lb'ers sitting right here...with just 80K on them.
 
haha dude im sorry man but u kinda suck at grammar and spelling. but cam that sumbish and be done with her. The remand injectors from ZZP are just cleaned up, painted white and sent out for a high price. I know this because i was stupid enough and bought some from them once before.
