Head games... So currently I have TEA/TFS215s on my 402, opened to 4" bore. Been a great head moved them over from the stock 346. Bought them new with 60cc, Ls3 hollow intake valve, powdered metal guides, using oem rockers with trunion upgrade. Curious on moving up to a TEA/TFS 235 or even TEA/TFS 245 head and use the same camshaft. Want to stay cathedral to use my FAST 102 intake. Think the gains would be there? I can sell my 215s to offset some of the cost and think there could be some pretty decent gains to be had. Any suggestions are appreciated.

Absolutely the gains would be there.
My .02 in order of preference.
MMS 235s, TFS 235s/AFR 230s, I think the TFS 245s have a
Intake valve & chamber designed for 4.060" Bore or larger.
The previously mentioned have an ideal valve size &
High velocity port size to feed a serious 4.00"+ Bore
& ~400" engine, especially with a FAST 102.

Haven't checked that but will. I thought the 215 and 225 were the same casting and the 235 and 245 were the same, but I could be wrong.
