I have a 98z28 m6 with tr230 cam and am putting a set of 243 heads on the car. I want to make sure I have all my ducks in a row as far as what i need to get. the heads are stock 243's. here is a list of what i need that i know of
ls7 lifters
ls2 lifter trays
head gaskets looking at cometic gaskets to bump compression
arp headbolts for pre 2004 ls
coil brackets
oil
filter

is there anything that i am missing?

I think you need the center bolt valve covers as well...you prop just left that I'm. I've thought about doing this as well.

does anybody know if ls1 coils will fit on truck coil brackets

You can presoak your lifters if you feel like. You really don't need to bump your compression in my oppunipn. Also lube the cam really good before you slide it in.

the cam is already been in for around 5k miles now. i will be swapping my valve springs to the 243's being they only have 5k

anybody know if ls1 coils fit on the truck coil brackets

what would my compression ratio look at with stock thickness gaskets? i bought the heads local from guy who has done alot of ls builds and he suggested .040 gaskets to get around 10.8 cr

Although ARP changes their recommended torque values from time to time, when I did my heads with ARP bolts they gave two sets of torque specs - one for use with ARP assembly lube and another for use with 30 weight motor oil. I would use the ARP assembly lube which is usually available from that sell the ARP bolts.

I would also lay in some water pump gaskets - pulling the water pump is a good way to get more coolant out of the block before pulling the heads.

Compression will be fine. Idkwhat it will be exactly but I put 243s on my Gto and camaro and it turned out great. If the cams been in for 5kthe already I wouldn't touch lifters or trays. Why fix it if it ain't broke type of thing. Id strictly do heads. And yes the coils will mate up identically on the brackets. Truck motor is what I've got now. Make sure to clean out the bolt hole really good. I used air duster and a tap the same size to clean out the holes. I use a razor to scrape the old gasket off then brake cleaner on the surface.

thanks for all the advise every bit helps!!! im only doing lifters and trays because they are under the heads and i will be right there. the bottom end does have 153k miles minus some katech rod bolts which have about 4k.
