Default help! im putting together my heads and cam set up

alright so my z28 is a 98 so it has parimeter bolts. i also have a broken header bolt inside the driver head.

so with that i have decided to get rid of those heads, and get some center mounts. now i am on a budge so parts will be used and new if not to expensive

so far...

i picked up some 853 casting heads today. center bolt and are already assembled. they have dual springs good up to 650 lift, and i got them with trickflow push rods 7.400 .80

now these heads have some port work done. the sheet where i got them from says they have a stage two job on them. idk what their stage two consist of but below is a chart showing some of the numbers. let me know what other numbers you may need i can flip through the pages he gave me.

as of now im not sure what cam to go with.

two members have custom cams i am interested in. they are both around the 630 lift range...

what cam would you guys suggest? i want to max out with the set up i have at hand. meaning with these heads, and bolt ons. maybe 150 shot down the road.

Okay, what I want is the port volume (example: 205cc stock, 210cc, 220cc, etc..)

I'd probably go with the 235/242 111+2 cam, but you'll definitely want to check PTV clearance.

How do i check that? Maybe i can get a thicker gasket to be safe? Also if those are the flow numbers i posted above is that decent or pretty much stock?
