p/v clearance on this set-up....please come in I got a set of stage two 5.7 l heads ported by total engine airflow, they were milled 30 thousands at first then 5 to clean them up this past time. I also have a thunder racing custom ground 231.4/227.9 .575/.569 on a 111.9 (+4 I believe). Will this fit without flycutting the pistons, or going to shorter pushrods? If I do have to go to shorter pushrods what would the total lift me then, im not sure how to do the equating. thanks alot.

Re: p/v clearance on this set-up....please come in I posted almost this same post not to long ago lol, All the replys I had told me to defineatly clay to measure p/v clearance. My heads are 5.7 milled .030 as well and the cam I was thinking about at the time was a tr 230 224, you'll prob be ok with the 7.4 pushrods but I can't remember exactly how to get the measurements, has something to do with base circle getting smaller while cam lift increases. There is alot of info on p/v stuff here. I'm sure others will chime in.

Re: p/v clearance on this set-up....please come in Stock length pushrods (7.4) is the length you need. So in that area your OK. However, I would use the clay method to make sure your not going to bend any valves.
