I am currently ordering parts form jegs and i have a couple questions

i am going to run the swirl port heads and i what to know the max cam lift can run?

or is i run the l69 305 heads what is the max cam lift with those??

any one order the np345 piston form jegs does it look like this?? there pics dont match?

 

The mechanical lift limit is roughly the same for either head unmodified, ~0.480" (assuming you get new valve springs).

The lift at which you get no further benefit is less with swirlport heads. I forget the number exactly, but something in the 0.450" range comes to mind.

Catalog pictures often don't reflect the exact part. Call Jegs about getting a single piston. Summit sells them for $12.95 each.

 

got any ideas on a good cam i should look for?

 

I believe I've discussed my opinions on those head choices.

If you are willing to get 1.94" valves installed in the 416 heads, and give them basic bowl and port clean-up, along with new valve springs, the Comp XE262 (mild) or XE268 (less mild) would be good choices.

 

my block is a 14093638 zz4 87-95 does it matter what cam i run can i use a old style cam??

 

also what gaskes set do i use if i run the 305 heads?? just the older set??

 

That's a roller block one-piece rear main seal block. I forget, do you have roller lifters now? If so, go with a roller cam (assuming the lifters aren't FUBAR'd). The Comp cams would be XR26x's.

Get the gasket set for the block, '87-up. The 350 head gaskets will be fine.

 

the motor i have is a flat tappet non roller. it has the mounts and holes for the roller lifters and all that. i just ordered the rod and tonight ill order the piston and bearings with rings.

i am going to see about getting 194's put in the l69 heads and new valve springs maybe get the valve guides cut so i can run a bigger cam. and screw in studs. port and polish and clean as much as i can.

if not just port the swirl ports and put them on.

 

I've seen used roller kits (lifters, anti-rotation dog-bones, spider, cam plate) on eBay. You'll need the shorter pushrods as well. Up to you which way you want to go.

I'd do what you said to the 416 heads before I'd spend a dime on swirlports.
