F22a4 Block.. ok to use?

F22A4 block.. IMHO pt 2

For the head.. I would replace everything while you have it apart to insure your motor has then the performance you could hope for once it is back together. You can get bronze valve guides for a inexpensive price. Valves are ranging from $160-350 and Good spring and retainers for $225-400.

If you want good performance from your motor, you have to make the head flow and a good proper tuning..

if you knew your shit, there's only 16 valve stem seals and not 32.

my example of no catalytic converter and catback system would be side exit exhausts on drag vehicles.
it also depends on the diameter of the tubing used and how it is stepped. granted, im talking about performance and not daily driving use.

actually if you knew your shit you would know that theres 32 stem seals..
16 valves , 2 seals per valve , 16x2=32 !

stem seals are split in half to fit around the stem of the valve , so get your facts straight before you correct people smart guy...

vehicles with side pipes still have a small restriction in the pipe itself to create some back pressure , look inside one of those pipes and you`ll see that the side of the pipes have little holes and a smaller pipe in that... tht causes some back pressure , or enough needed.. mind you that vehicles with side pipes usually are V8`s that don need much back pressure , unlike our little 4 cylinders...
so please look for a better example, entertain me!!!

WRONG.
does that look like a two piece buddy? i work in a machine shop so ive worked with all kinds of valve stem seals and never in my fucking life have i seen a two piece design for a HONDA.



the collector will provide enough backpressure for a NA vehicle and like i said, it depends on the tubing diameter, length and how it is stepped. anything else is a restrictions.

look at forced inducted applications, they dont even come to a collector aka zoomies or look at the top fuel motors.

yea oops i was talking about the valve keepers hahahahah
my bad bro !
