just curious if any know oh any companies that make 33mm intake valves for the p75,p4 ls head?

my only other option I wanted to try the older lude b21a1 valves as they are 33mm but .55" shorter stem dont know how much of a difference the stem length would make. p8r valves are the exact size i need but can't find a part # for them from honda. Any advice would help and no I'm not goin with a vtec head on the is build. vtec is for the sleeved block.

no one makes one. that would be +2 mm.

actualy endyne will make them and the question was. How would the .44" difference in length affect the valve travel or spring?

not bein a dick just the fact you only pointed out the obvious they are +2mm

I believe the h22a intake valve will fit, but you will have to change out the valve guides with some guides with the same diameter of the ls and the inner hole diameter of the vtec valve guides. you can use vtec dual valve springs by swapping the valve seat with a vtec seat and using the ls retainer.
