how much compression do i need to get some decent #'s out of these cams? planning on using a mugen head gasket. should i also mill the head? if so, how much or should i go with flat valves and call it a day? also while the heads at the machine shop, how fast can most places do a valve job and is it heard of to do a valve job w/o doing port work? sorry for all the questions. thanks

 

i need to know this to anty helpers

 

You dont really NEED more compression with toda A's.. MOre would help though. i think anywhere from 10:1-12:1 will be ok for those cams since they're really mild. basically the same as a CTR cam with a tad more duration.

call portflow or alaniz about the valvejob and see what they say. If you got a b16, i'd say 2 piece headgasket and flat valves since you got the head off anyway. or use a stock head gasket and have the guy doing the valve job mill it .010"

 

if i'm uppin the compression that much then i might as well just put in some ctr's and use b's instead of a's. u think?

 

Yeah but with CTR's and toda B's you need to watch out for valve Clearance.

 

what about ctr's and m22's?

 

Talk to Clean Rice about M22's. He'll give you some good info.
