Intro to a port job
For the street would it be better to have the Nitro valves in the heads or are the Edelbrock valves sufficient?
I would think in something that held tune, like stays in the same elevation and basic weather that any stainless would be fine, the eddys included. If you drive all over...and it's a ragged edge motor, I like the nitro's. Btw I requested they milled them .025..so you should be right at 65cc...they could only do .010 and then it kissed the chamber cut of the valve job. I also bought new valve stem seals for the both... because on another set they did coteco seals, the white one..I gave up on those. They wear the stems and dont hold oil back better than other anyhow. Yours were black ones..no name, builder stuff idk. I'll send them as well, I won't use them.So you now have trickflow vitons. #tfs 52400454. To those reading-The 522-16 is the comp number for 3/8 .530 metal, they are a one time seal, press on and use up. If I wouldn't choose them myself, i dont use them on others.Btw I picked up a kwikway setup. I need a facer now.
Another thing.. the coated nitro valves would require clearance in your guides, they barely fit. ..which lends another thought. That they may be a good drop in a refresh where the guides are broke in and on the high side.
Since I'm typing I went ahead and took my brother-in-law's 318 heads back after checking the guide clearance on them and found .006 int and .008 exhaust ..roughly up to as much as .009
I set them right in front of the owner, hooked up my dial and mag base, 90'd to the stem...and said see...
He said he would fix immediately and began yelling across the shop. I check everything, that's what you get with me.
I've realized I'm kind of perfectionist.
I edited this.
