I'm getting a set of heads for my 408 build that were originally done for an all bore 388. The friend that I'm getting them from currently has them on a 346 with a stock bottom end with an LS1 hotcam. I figured I'd slap them on my stock motor until the 408 is actually together. I'm running a TSP 231/237 .598"/.595" lift cam on a stock bottom end. Will I have piston to valve clearance issues with a set of heads with 2.08" intake and 1.60" exhaust valves? As far as I know, the heads are not milled.

i asked the same question a while ago, got those valves but mine is milled .030 and they said yes you would have a p/v issue

I know with a 2.02 vavle I heard that a F13 sized cam was the largest you could go with...if thats the case theres no way your setup will clear.

I've run my engine to 7000 rpms with the 231/237 and 2.055/1.60 valve 59cc head combo with no issues, however, I don't know how much the extra 0.025" diameter will affect your clearance.

I ordered the TR230/236 595. 598 cam, but when i got it, it was 231/237 .594 .604. When I spun it over with check springs, the valves hit. I had to flycut the pistons. My Stage II heads were shaved .012, 2.02 and 1.60 valves.

I was just using the felpro gray graphite looking gaskets. Just standard thickness.
