?S about pistons and rods.

you can steam clean the valve but valve job is not a MUST unless you want to improve ponnie output

cool, i look into the steam cleaning. i just want to keep the price fairly low, what is a MUST when rebuilding?

thanks

You can squeeze more hp by tuning cam or changing cam than valve job. its all about money spend efficiently to squeeze max hp per dollar.

have all the moving part in spec, correct clearance. correctly torqued, correct balance. They are all for reliability. Power output offsets reliability.

if u do forged rods and pistons, new rod and main bearings, oil pump, water pump, oil squirters, all new gasket (oil pan, head, valve cover, etc.) timing belt. pretty much all new stuff that can wear out and damage ur new forged motor u just threw a few grande at. do it right, keep it safe.

yea, i am not trying to squeeze power, just trying to build an efficient engine that will not be problematic in the long run.

follow what i said if u do a build. if u got a new set of nice rims would u put the old set of bald tires on it?

you definitely dont need a valve angle job, but you do need what dandan2 named.

no sir, of course ill replace all gaskets, timing belt, water pump, ect. just looking for what MUST be down to top and bottom end like honing, resurfacing, valve related stuff.

clean the head and atleast do valve seals, they are only 60 bucks and will make ur top end like new.

thats what i was looking for

where can valve seals be found?

cylinder head:

cleaning, decking, replace valve stem and seals, check valve clearance. clean valve carbon.


engine block:

cleaning, check for flatness on the surface (warpage), check cylinder wall damaged mark if any, and the inside diameter to make sure the wall is weared too much, overbore or not. If not you need to hone the surface of cylinder wall.

Crankshaft:

cleaning, check for bearing journal if they are within spec, damaged or not. Put bearing and use plastigauge to check the cleareance.

Piston & rods: weight match them, ask a shop to do it.

thats all i ccan find out for now.

great info, thanks man. (thumb)

a good 5 angle valve job should restore ur head and make ur top end like new again, just like ur bottome end. its not really needed but affordable and would freshin things up.

I'd recommend against a 5 angle. A standard 3 angle valve job is more than adequate. 5 angle jobs have the "more is better" attitude surrounding them when you can actually hurt performance if you don't cut at the correct angles. Every make of motor needs something different and its best not to use generic angles.

A leak down/pressure test should be performed on a cylinder head before you reuse it, even if it came off a good running motor.
