if i go 1mm oversized on the valves with a 3 angle valve job would it be worth it, or should i just get the valve job? im going for 500rwhp.

also should i get the head ported and polished? would it be worth it aswell?

if o go oversized with the valves what else would have to be upsized? would the stock cams run oversized valves ok?

You should redo your whole valve train and do the 3 angle valve job with those HP goals IMO.

Stock cams are fine. Just make sure the shop gets the clearances right.

Is it worth it?

I think so but cost will be a factor as quality work isn't cheap.


Same here...head flows better, but it's not cheap!
