I finshed taking my heads off this morning.It is a 351W.In my other thread I am looking into purchase some new heads.The engine has flat top pistons with valve reliefs.If I purchase a set of heads with 202 valves this should work fine? I am running a Trick flow stage 1 cam.Also I noticed the intake gasket ports are smaller than the head ports,but match the intake fine. Heads have been ported and polished.Would this give any problems with the car smoking?See the car smokes and I have run compression test and leak down test and I have an average of 2-4% leakage which is good.I just figured the heads needed rebuilt since I sae a lot of oil carbon build up on the valves when I looked in the intake ports.Thanks.
 
i don't think too many guys here run 351W's so you may need to look elsewhere for someone with an actual setup. However, if you have valve reliefs, the 202 valves will probably fit. I don't know the specs off hand for the stage 1 cam, but as long as it's not too wild, you should be fine. sorry i couldn't be of more help.
