front wheel drive block 87 3.8

so the head gaskets are on the way.

timming map ? anyone ? please !

other issue i have is me idle , and its something i'm hopping raising the compression, tighter quench and degree-ing the cam will help,

my idle i have to run around 13.7 afr at idle otherwise it will start surging then stall. i wouldn't think this is typical of the buick v6.

another thing is i have seen a photo of a turbo trans am engine and it has the same valve covers as mine ( with the 3 acorn nuts on top )

is there a easy way to install roller rockers on those ? since the only problem is the cover is held on by the rocker studs. just thinking of a way of making this work. i think a typical rocker would work with a long set screw as the locking screw and then the nut will hold on it.

The TTA has FWD heads. That's why they look like yours.

^ figured ... so what do they do for roller rockers and such ?

 

[frank_ster]

got a question ,, i'm not sure the fwd heads use 1.55 ratio rockers. i would think they are the same as the tta heads any one have any info ?

i want to change to roller rockers, the exhaust valve stems are getting sharp and mushroomed a bit.
should i go with the 1.55 rockers or get 1.6 ratio ? i have a 0.504" lift cam when used with 1.55 ratio. any down side to going 1.6 ? flow issues ?
