Serious 340 build into 361 HiRPM Screamer
Cant help ya, I have no experience
I was told by many people that you must pull the heads to get the tall hyd rollers out. I was able to pull them all out of my LA 340 with the X heads in place.
I did pull the heads to have them ported but thats a different story.
Sorry to hijack the thread
Me bad
